Who's is the contraction for 'who is', and party's is the possessive form of party. Option A correctly uses both.

In the clause "beard was wonderfully whimsical", "whimsical" is a predicate adjective that directly describes the noun "beard". "Wonderfully" is an adverb modifying "whimsical", while "gloriously" and "witty" modify "uncle's".
