Supposedly HIZ move and A bands don't.

I'm guessing that the answer is C

a A band WHICH IS CONSTANT

B is the z disc ( unaffeceted

C is the i band ( areas of actin not overlapped by myosin

d nucleus

I thought A was t-tubules and F was the A band.
I'm guessing that E is the sarcoplasmic reticulum

intercalated disc

Choice E
