Correct answer
B. Conus arteriosus
Step-by-step solution
The heart of a frog consists of three chambers: two atria and one ventricle. The ventricle opens into a sac-like structure on the ventral side of the heart known as the conus arteriosus.
The sinus venosus is a triangular structure on the dorsal side of the heart that receives blood from the major veins (vena cava) and opens into the right atrium.
