A: IP, R ball, 1st and 10 from the R30
B: IP, R ball, 1st and 10 from the R25
C: IP, K ball, 1st and 10 from the K40
D: Nothing, R32 didn't realize his helmet came off.

The corrected part of your play doesn't address the issue. The helmet coming off is not a foul; the next block is.

If the helmet-less player blocks during the kick, it's previous spot enforcement, which would make C the correct answer.

If the helmet-less player blocks during the return, the basic spot is the end of the run (R45), and the foul by the offense was committed at the R40. Under ABO, we'd enforce from the spot of the foul, which would make B the correct answer.
