The sentence "She runs every day" displays correct subject-verb agreement.

In order to determine which sentence displays correct subject-verb agreement, we need to understand the basic principle of subject-verb agreement.

Subject-verb agreement means that a verb must agree with its subject in terms of number. In other words, if the subject is singular, the verb should be singular. If the subject is plural, the verb should be plural.

Let's take a look at some examples of sentences and identify the correct one:

1. The dog runs in the park.
2. The dogs runs in the park.
3. The dog run in the park.
4. The dogs run in the park.

To identify the correct sentence, we need to analyze the subject and the verb. In this case, the subject is "dog" or "dogs," and the verb is "runs" or "run."

Sentence 1: "The dog runs in the park." - This sentence displays correct subject-verb agreement because the singular subject "dog" matches the singular verb form "runs."

Sentence 2: "The dogs runs in the park." - This sentence doesn't display correct subject-verb agreement because the plural subject "dogs" doesn't match the singular verb form "runs." It should be "The dogs run in the park."

Sentence 3: "The dog run in the park." - This sentence doesn't display correct subject-verb agreement because the singular subject "dog" doesn't match the plural verb form "run." It should be "The dog runs in the park."

Sentence 4: "The dogs run in the park." - This sentence displays correct subject-verb agreement because the plural subject "dogs" matches the plural verb form "run."

Therefore, the correct sentence that displays subject-verb agreement is: "The dog runs in the park."
