Question

Which sentence uses punctuation correctly?

A.
My only pet, which is a ball python sleeps during the day.

B.
My only pet which is a ball python, sleeps during the day.

C.
My only pet, which is a ball python, sleeps during the day.
( i think its b)

Answer 1

b is not the correct answer, because we did not set off the phrase on both sides with punctuation

Answer 2

the appositive phrase which is a ball python could be left out of the sentence
and we would still have a complete sentence

Answer 3

''My only pet sleeps during the day'' - that tells more about the pet
we set that phrase off with punctuation before and after the appositive phrase
which answer A B C has punctuation in both places?

Answer 4

sentence A has a comma after pet before the appositive phrase
"which is a ball python" but only sentence C has the comma in both places to surround the appositive phrase. ''My only pet, which is a ball python, sleeps during the day''
do you see how the commas let us know that we have a phrase that tells more about the pet?
