B Correct answer
Explanation

Under the postal rule, acceptance is complete when posted, but revocation is only effective when it reaches the offeror. Y can revoke acceptance anytime before the acceptance letter reaches X, but not afterwards. This is because the acceptance is already legally effective upon posting, so revocation must be communicated before that moment to prevent contract formation.
