Final answer:
The condition of the court at the end of 'The Holy Grail' Idylls of the King is described as peaceful yet melancholic, indicating a state of decline and sorrow. Option C is correct.
Step-by-step explanation:
At the end of 'The Holy Grail' from 'Idylls of the King' by Alfred, Lord Tennyson, the court is depicted as being in a state of sorrow and decay. This description aligns with option C, where the court is at peace, but a sense of melancholy prevails. The passage provided describes a sense of loss and the passage of a more glorious time into memory.
The lines 'But evil things, in robes of sorrow, Assailed the monarch's high estate' and 'An old, mad, blind, despised, and dying king' evoke imagery of a court in decline, reinforcing that a once-great court is now overshadowed by an air of sadness and impending doom.
