Answer:
A.
Step-by-step explanation:
Parallel structure or parallelism is the repetition of the same pattern of words in the same manner to emphasize the importance of all words. A particular grammatical form is chosen to compare the words.
For example,
- I like dancing, singing and reading.
- I like to dance, sing and read.
A particular grammatical form of parallelism and commas usage that's been applied in the sentence is in option A.
So, the correct option is Option A.
