Zero homework...go with D...

I know C is true, A and B are false. D, hrm. I think it was true but hasn't been for a bit. I think people still do it even.
Final answer, C only. No google.

Any one knows what year no NM above 3 stories was changed to type of construction.

C.
Because:
EMT is permitted in plenum ceilings
NM cable is not permitted in multi-unit dwellings above 3 stories
EMT is not permitted in wet locations

EMT is permitted in wet locations when treated with the corrosion resistance coating.

EMT is permitted in wet locations when treated with the corrosion resistance coating.

Look at post #2 and post #3.

Look at post #2 and post #3.

I don't understand. I looked back to the 2005 and it says the EMT can be in wet locations providing it has the coating.

This is the New York City electrical code amendments.
