during a life cycle of adult lancet fluke live in cows. They spread their eggs in cow manure, snails eat the eggs and the immature parasites hatch and infect their intestine. The snail coughs up these offspring in balls of slime and ants eat these slime balls loaded with flukes. The flukes migrate to the ant’s head and make them climb to the tops of grass blades where they are eaten by cows and the cycle starts over again

a. Only ant act as inntermediate host 

b. both snail and Ant act as intermediate host

c. cow act as definitive host due to sexual reproduction

d. only snail act as intermediate host due to asexual reproduction

Typically as cells grow, their increase in volume outpaces their increase in surface area, and continued survival requires undergoing asexual reproduction to reestablish a healthy surface area to volume ratio. Thus, which of these is least likely to contribute to the ability of a single-celled foraminiferan to grow to a diameter of several centimeters?
