Solution

The correct option is C Tympanum, sternum and lacrimal glands
Amphibians are the earliest group of tetrapods and show dual mode in their lifestyle i.e. they live in water as well as land. Sternum developed for the first time in them which further helped to form ribcage. Tympanum, lacrimal gland and harderian gland also appeared the first time in this group. So, the correct answer is B.
