2. Hasil penjumlahan pecahan dari 7/12 + 5/12 adalah... D. 12 A. 1 B. 2/12 C. 35/12

I think that it's B. Because birds have back bone so that eliminates C and D.

The correct answer is option a. tunicate, which has a notochord during its larval stage but lacks a backbone in its adult form. Fish and birds, on the other hand, possess a backbone and do not meet the criteria. Thus, tunicates are the best example in this context.
