Read this excerpt from "the lady of shalott" by alfred, lord tennyson. how is the isolation of the lady emphasized through the poem's settings?

on either side the river lie
long fields of barley and of rye,
that clothe the wold and meet the sky;
and thro' the field the road runs by

to many-tower'd camelot;
and up and down the people go,
gazing where the lilies blow
round an island there below,
the island of shalott.

a. she lives in a building that is not known to anyone.
b. while she lives in camelot, she cannot leave her tower.
c. the town has fields and roads, but she lives in a secluded tower.
d. she lives in a place that is far away from the road to camelot.
e. she is surrounded by gray stone walls in the tower.
