Select the correct sentence:

A) She is younger than he and I.
B) She is younger than he and me.
C) She is younger than him and I.
D) She is younger than him and me.
My answer A I feel like C could be the right one also

C is totally wrong because you've used both an object and subject pronoun.

A is correct.

To determine the correct sentence, we need to consider pronoun case and usage.

In this case, the pronoun "he" and "I" are being compared to "she" in terms of age. We need to use subject pronouns (I, he) or object pronouns (me, him) based on their roles in the sentence.

Option A) "She is younger than he and I." is using subject pronouns "he" and "I." This sentence could be correct if we break it down into two separate comparisons: "She is younger than he" and "She is younger than I."

Option B) "She is younger than he and me." is using subject pronoun "he" and object pronoun "me." This creates inconsistency because we should use the same case for both pronouns. Therefore, option B is incorrect.

Option C) "She is younger than him and I." is using object pronoun "him" and subject pronoun "I." This creates inconsistency because we should use the same case for both pronouns. Therefore, option C is incorrect.

Option D) "She is younger than him and me." is using object pronouns "him" and "me." This sentence is correct because we are comparing "she" to "him" and "me" as objects in the sentence.

Hence, the correct sentence is option D) "She is younger than him and me."
