Which operation would involve neutralizing hostile minefields?

The correct choice is indeed associated with Mine Warfare, which specifically focuses on the strategy and tactics used to manage and counter underwater mines. This operation involves neutralizing hostile minefields to ensure safe passage for naval vessels and to protect allied maritime operations. Mine Warfare encompasses a variety of techniques, including mine sweeping, mine hunting, and the use of underwater vehicles, which are all crucial for mitigating the threats posed by naval mines.

This area of warfare is critically important because minefields can significantly restrict movement, disrupt naval operations, and pose dangers to both military and civilian ships. By neutralizing these threats, Mine Warfare enables freedom of navigation and contributes to overall maritime security.
