Answer:

Option A, most closely related to mammals

Explanation:

Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.  

All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other

Hence, option A is correct
