Final answer:
The bride mentioned in the criticism of the upper class is about to marry Sir Lancelot. This example is found in the poem 'The Lady of Shalott' by Alfred, Lord Tennyson, which uses Arthurian legend characters to convey themes and criticisms.
Step-by-step explanation:
The bride in the author's criticism of the upper class is about to marry Sir Lancelot. The reference to Sir Lancelot is seen in the lines:
A bow-shot from her bower-eaves,
He rode between the barley-sheaves,
The sun came dazzling through the leaves
And flamed upon the brazen greaves
Of bold Sir Lancelot.
Alfred, Lord Tennyson's poem, 'The Lady of Shalott', indirectly criticizes the upper class through the character's fascination and eventual doom sparked by the sight of Sir Lancelot. Tennyson uses the legend of Sir Lancelot to portray the allure of the upper class and its potential to cause ruin to those who become too entranced by it. The character of Sir Lancelot is well-known from the legend of King Arthur, who is part of English history and lore.
Therefore answer is b) Sir Lancelot.
