Which type of fuzes is triggered by proximity to a target?

The correct answer is C. Proximity fuzes are designed to activate when they come close to a target, utilizing various methods such as radar, infrared, or pressure sensing to detect the presence of the target. This type of fuze allows for an explosive device to detonate at the ideal moment, typically when it is near or has a chance to engage the target effectively.

Proximity fuzes are especially useful in air-to-ground munitions, as they can achieve a higher probability of hitting the target compared to methods that require direct impact. The technology ensures that the explosive detonates right before reaching the target, maximizing effectiveness and damage.

In contrast, other types such as point detonating fuzes require direct contact with the target to trigger an explosion, whereas delay fuzes are designed to activate after a specified time, often used to create a time gap for tactical advantages. Time fuzes rely on a preset timer based on clock mechanisms, which is not dependent on any proximity to a target. Each of these alternatives lacks the specific capability of proximity fuzes, which distinguishes it as the correct choice in this context.
