Explanation:

Parallelism or parallel structure means finding the balance between one or more than one sentence that has the same sentence structure. This is achieved by connecting a clause(s) with a coordinating conjunction such as or, and, not, but, so, etc. This is done to make texts easier to read.

Option B is the sentence with parallel structure because it used the coordinating conjunction or to join the two clauses and using the phrase to write to make the sentence have meaning and easier to read and understand.
