24. Select the sentence that is grammatically correct.

Answer: B

Explanation:

The nurse spoke to my sister and me about our mother's condition.

This sentence is grammatically correct as it uses the objective case "me" appropriately after the preposition "to."

A) The nurse spoke to my sister and I about our mother's condition.

This option is incorrect because "I" is a subject pronoun and should not be used as the object of a preposition. The correct form should be "me."

B) The nurse spoke to my sister and me about our mother's condition.

This option is correct as it uses the objective pronoun "me" correctly in the context of the sentence. The phrase "to my sister and me" follows the preposition "to," making it grammatically sound.

C) The nurse spoke to me and my sister about our mother's condition.

While this option is grammatically correct, it is not the selected answer. It still effectively uses the objective pronoun "me" correctly in the context of the sentence.

D) The nurse spoke to I and my sister about our mother's condition.

This option is incorrect because "I" is a subject pronoun and should not be used as the object of the preposition "to." The sentence should use "me" instead.

Conclusion

Option B is definitively correct as it appropriately uses the objective pronoun "me" in the context of the sentence. The other options fail due to the improper use of subject pronouns or variations that do not adhere to standard grammatical rules. This highlights the importance of understanding pronoun cases in English grammar.
