Answer: It's strange that we have the same birthday.
Explanation:
The option "that we had" would be wrong because the verb in the past form (had) is not the tense used in the sentence. The option "for we to had" presents the same issue, in addition to incorrect use of the subject: "for us to have" could have worked, and it would still be an unusual sentence. The option "that we do" uses the verb "to do" instead of "have", which would be the correct verb for a birthday. "that we have" is correct because it has the past tense and the verb "have".
