· Evacting is incorrect; the correct spelling is Evicting. Evicting means to forcibly remove someone from a place they occupy, which fits in the context of military action against an enemy.
· Other words like Recapture, well-fortified, and priority are spelled correctly. "Recapture" means "capture (a person or animal that has escaped)". "Well-fortified" means "something or someone has been made stronger or more secure". "Priority" means "the fact or condition of being regarded or treated as more important than others".
Hence, option (a) is the answer.
