Boy this one is a crazy one. This is what I know:
"The National Electrical Code (NEC) allows RSC, IMC and EMT to be installed in concrete...."
Not IMC, might corrode.
Not EMT, might corrode.
Not Flex, will leak....
Answer: Rigid.

LOL...HAHAHA
yeah, I saw your misread earlier. just wanted to see if you realize that
OK, so anyway, there's only 2 of you interested in this fun question heh...
The ans. is "2". are you scared yet!!
And if you want to know the explanation, it's going to be as odd as the other question I put in about "plumbing". which didnt' convince me at all.
pretty crazy eh..

Ok Far: I call Uncle.
I gave this to my EE and he simply shook his head and said "good luck on that one if it not Flex."
He did say that some types of concrete are more corrosive that others and that EMT, if not properly protected, will corrode.
So, what is reasoning? I've read the plumbing one too, and it confuses me too.

From a related website:
Article 358.10 (NEC) outlines the permitted uses of EMT. It can be used indoors as well as outdoors, exposed and concealed, in applications where a less than maximum amount of protection is required. In addition, it can be used underground and in concrete with restrictions — with supplementary corrosion protection in some cases. However, rigid nonmetallic conduit (RNC — gray PVC) can be more economical and entirely suitable in these environments.

this question came directly from ARE test bank, word for word. I didn't lie.
And this question here comes directly from Kaplan.
Q: Which type of conduit may not be embedded in concrete?
1. Rigid
2. Armored cable
3. EMT
4. Flex
the ans. is Armored. I buy this. Cool with me. Problem is ARE and Kaplan sometimes don't agree with each other. So, If they throw me a ques. like this with 4 options like above, I will hate them very bad. Because, obviously, ARE test bank said EMT is not acceptable.....urgh....

Far: Your orginal post had no mention of armored cable.
Q: In a commercial building, the electrical conduit system is to be embeded in the concrete slab. Which of the following is unacceptable?
1. IMC
2. EMT
3.Flex
4. Rigid
What's going on? Your questions do not match up?

that is the whole issue.
The first question came from ARE test bank
The second question came from Kaplan test bank.
And if I happen to have this question with Kaplan's options where both EMT and Armored are in there, I will be really, I mean, really mad. know I mean...

Armored cable is not conduit. It's a conductor. So if you do get the latter question, you should pick armored cable. I still can't imagine encasing flex in concrete. Anyone have the NEC handy?

Son of a bitch!
Check this out: http://www.cantexinc.com/cantexinc/Products/Schedule_40/Flexible_Conduit_and_Accessories/EZ_Flex_Coils.php
Look at the FAQ's.
This just proves that we must watch our preconceptions.
"Flex" does not always mean metallic flex!

Hi Far,
The second question asks, "what conduit" and clearly, armored cabled is not conduit, so that would be the answer to that one.
EMT can be embedded in concrete, but is the least desirable in the first question.
It that all right?
Good dig up Coach.
