To determine which of the sentences demonstrate correct subject-verb agreement, let's analyze each sentence:

a. The children visit their grandparents last weekend.
In this sentence, the subject "children" (plural) does not agree with the verb "visit" (plural) in present tense. Moreover, the phrase "last weekend" suggests past tense, while the verb "visit" is in present tense. Therefore, this sentence does not demonstrate correct subject-verb agreement.

b. They visit their grandparents last weekend.
In this sentence, the subject "they" is a pronoun that can refer to both singular and plural nouns. However, the verb "visit" is still not in agreement with the past tense implied by the phrase "last weekend" (visited would be the correct past tense form). Therefore, this sentence does not demonstrate correct subject-verb agreement.

c. The visited their grandparents last weekend.
This sentence lacks a subject. The sentence is missing the subject "they" or "children" before "visited," making it incomplete.

d. The children visited their grandparent last weekend.
This sentence demonstrates correct subject-verb agreement. The subject "children" (plural) is matched with the verb "visited" (past tense) to show agreement in number and tense. The possessive pronoun "their" is also used correctly to indicate ownership. The phrase "last weekend" also matches the past tense.

Therefore, the correct sentence is d. The children visited their grandparent last weekend.
