(B) The life cycle of the liver fluke ($Fasciola$ $hepatica$) involves several larval stages that occur in a specific order within its hosts.$1$. The cycle begins with the egg,which hatches into a ciliated larva called the $Miracidium$.$2$. The $Miracidium$ enters the intermediate host (snail) and transforms into a $Sporocyst$.$3$. The $Sporocyst$ then develops into the $Redia$ stage.$4$. The $Redia$ produces the $Cercaria$ larvae,which emerge from the snail.$5$. Finally,the $Cercaria$ encysts on aquatic vegetation to become the $Metacercaria$,which is the infective stage for the definitive host (sheep/human).Therefore,the correct sequence is: $Miracidium \rightarrow Sporocyst \rightarrow Redia \rightarrow Cercaria \rightarrow Metacercaria$.

The correct sequence of various larval stages in the life cycle of the liver fluke ($Fasciola$ $hepatica$) is:
