The bishop sadly declared that the poor gentleman who was dead was quieter of the community.

The correct substitution is "the quietest".
Explanation:
· "Quiet" is a gradable adjective, meaning it can have comparative and superlative forms.
· The superlative form is needed because we are comparing one person (the gentleman) with the whole community.
· "The quietest" is the correct superlative form.
Grammatical rule used:
· When comparing more than two things, use superlative adjectives (the + adjective + "-est" or "most" + adjective).
· For one-syllable words like "quiet," we add "-est" in the superlative form.
Example:
· Incorrect: He was quieter of the group.
· Correct: He was the quietest of the group.
Meanings of other options:
· Most quiet (awkward phrase, not commonly used).
· Quiet (adjective but not in superlative form).
· The quieter (comparative form, but superlative is needed).
