b. <em>dead members of the community in their graves </em>, this is the correct option.
Thomay Gray, a XVIII English poet, is contemplating the situation: the source of inspiration of his poem ,"Elegy Written in a Country Churchyard". Through this elegy, he will lament death but the villagers' death mainly. "<em>The rude forefathers of the hamlet ......", </em>this line refers<em> </em>to<em> </em>the simple ancestors from the town, who are the poor villagers. These are buried in the churchyard: " <em>narrow</em> <em>cell forever laid.</em>..// ...<em>sleep</em>.."
The following options are wrong:
a. the townspeople asleep in their beds . The poet uses metaphorical language ; he uses the word "sleep" to mean dead.
c. prisoners in the town jail . The poet uses the word "cells" metaphorically to mean graves. He also uses the word "rude" to mean simple.
d. townspeople who died in prison. Same explanation as above.
