In which sentence are parentheses used correctly?

a. landscaping (with native plants provides) a habitat for native creatures such as butterflies, birds, and wildlife.

b. landscaping with native plants provides (a habitat for native creatures) such as butterflies, birds, and wildlife.

c. landscaping with native plants (provides a habitat for native creatures such as butterflies, birds, and wildlife).

d. landscaping with native plants provides a habitat for native creatures (such as butterflies, birds, and wildlife).

Parenthesis are normally used in a sentence to give us extra information of the topic within the sentence. It must also be grammatically correct when using parenthesis, or else you're just adding confusion.

For example:

I went outside (around 3-4 A.M) to find a deer in the moonlight.

around 3-4 A.M was not needed to give us a complete statement, but helped give us additional information to structure the idea better.

Now, with that information given, let's figure out which sentence uses parenthesis best.

A.)
A. Landscaping (with native plants provides) a habitat for native creatures such as butterflies, birds, and wildlife.

Let's rewrite the sentence without the words in parenthesis.
Landscaping a habitat for native creatures such as butterflies, birds, and wildlife.

This doesn't appear to make any sense, as it's just a sentence that would have no place in a paragraph, and is grammatically incorrect.

B.)
B. Landscaping with native plants provides (a habitat for native creatures) such as butterflies, birds, and wildlife.

Let's rewrite the sentence without parenthesis.

Landscaping with native plants provides such as butterflies, birds, and wildlife.

This doesn't make any grammatical sense as it doesn't tell us what it provides on it's own.

C.)
Landscaping with native plants (provides a habitat for native creatures such as butterflies, birds, and wildlife).

Rewrite without the parenthesis.

Landscaping with native plants.

This, once again, doesn't appear to make much sense. It could if you were to reply to a question, but it does not stand as a sentence alone.

D.)
Landscaping with native plants provides a habitat for native creatures (such as butterflies, birds, and wildlife).

Rewrite without parenthesis.

Landscaping with native plants provides a habitat for native creatures.

This makes sense, and the parenthesis provides additional information to help us understand the idea of the sentence better.

D.) Is your correct answer.

I hope this helps!
