What information do C-scopes provide?

C-scopes, also known as combination scopes, provide essential information regarding the bearing and elevation of targets. This instrumentation is widely used in various naval operations to enhance situational awareness and assist in target acquisition.

The bearing indicates the direction to the target relative to a reference point, which is crucial for navigation and engagement decisions. Elevation gives the vertical angle relative to the horizontal plane, allowing personnel to understand at what height or declination a target is found. Together, these two pieces of information are critical for accurate target tracking and engagement, especially in maritime and aerial scenarios where both horizontal and vertical positioning are dynamic.

The other options focus on different types of target parameters that are not typically provided by C-scopes. While they may be relevant in other contexts—for instance, elevation and distance would be significant in certain radar applications—the specific capabilities of C-scopes are mainly focused on the bearing and elevation aspects, making option B the correct answer.
