I almost know this SC by heart.

idiom is "mistook for"

C changes meaning. It seems as if the moon(it) was rising to attack.

whenever you see "for", be on the look out for changes in meaning.

if you see "X for Y", slight movement of words here and there can change the meaning.

I'm running short of examples here

B

rising (of moon ) was considered as an attack and not the moon as an attack. Also the idiom is mistake X for Y .

One more vote for B.

The correct idiom is indeed mistook for.

BTW.. other variations are correct too - like, mistake for, mistaken for
