While I do not have the book and cannot give specifics
for similes, look for anything comparing two things with like or as
(he ran"like" a giraffe on stilts)
( she was "as" round as a balloon)
for metaphor it compares without like or as
( the girl was a cat sneaking up on her prey)
The answer is A. Present progressive
Sequence or I’m not really sure I suck at these things I’m sorry
