Choice A rationale:

 Picking and squeezing acne lesions is not recommended to prevent scarring.

In fact, it can lead to more extensive inflammation and potential scarring.

This choice is incorrect and can exacerbate the issue.

Choice B rationale:

 Avoiding excessive sun exposure and using non-comedogenic sunscreen is a crucial recommendation to prevent scarring in acne vulgaris patients.

Sun exposure can worsen hyperpigmentation and make scars more noticeable, so protection from the sun is essential.

Choice C rationale:

 Scarring is not inevitable with acne vulgaris, and this statement is incorrect.

Proper management, including medication adherence and appropriate skincare, can help minimize scarring.

This choice is misleading.

Choice D rationale:

 Scrubbing the face vigorously to remove acne lesions is not recommended.

It can lead to further irritation, inflammation, and potential scarring.

This choice is incorrect and can harm the skin.
