Sentence Correction: Parallelism - A and/or/but B

When outdoors for long periods of time, it is important to apply protective lotion and to wear a hat as it can prevent harm from UV rays.

Incorrect.

This answer choice is grammatically incorrect and repeats the original mistake. A pronoun (in this case, it) refers to a previously mentioned noun. If we wish to refer to a previously mentioned verb (in this case, applying lotion and wearing a hat), we need to use the phrase to do so or doing so.

Very well done!

This answer choice corrects the original Pronoun error by using the phrase as doing so to refer to a previously mentioned verb or verbs (in this case, applying lotion and wearing a hat).

It also maintains parallelism according to the Stop Sign:

A and/or/but B

Incorrect.

Although this answer choice corrects the original Pronoun error by changing the pronoun it to doing so to refer back to the verb (in this case, wearing a hat), it makes a Parallelism mistake and is grammatically incorrect. The construction A and B requires that A and B belong to the same part of speech. In this answer choice, A is a noun (protective lotion) whereas B is an unconjugated verb (wearing).

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

A and/or/but B

Incorrect.
