Final answer:
The correct pronoun for the movie titles is 'A) He' as in 'He Came to Dinner' and 'The Man Who Shot Liberty Valance'. Pronoun usage is evolving to include non-gendered forms like 'they/them/their' in certain contexts for gender-neutral language.
Step-by-step explanation:
The pronoun that precedes "Came to Dinner" and "Shot Liberty Valance" in movie titles is A) He. The titles of the movies are "He Came to Dinner" and "The Man Who Shot Liberty Valance."
In language, pronouns like he/him/his are traditionally used when the gender is known to be male, but there has been a recent shift in using they/them/theirs when gender is unknown, unimportant, or when someone prefers non-gendered pronouns. Grammatical agreement with indefinite pronouns like everyone is also essential to maintain clarity in both written and spoken English.
