What are the four important conductors in an RGsB signal?

The correct answer highlights the key components of an RGsB signal. RGsB is a composite video signal format that utilizes both the red and green channels for color information, along with a sync signal that includes both horizontal and vertical sync pulses to ensure proper image timing. The inclusion of a signal ground is critical as it establishes a reference point for the other signals, assisting in maintaining a stable and noise-free signal transmission.

The presence of horizontal and vertical sync in the sync conductor is essential for accurately rendering images on a display, as sync signals tell the display when to start a new line or frame. Thus, the combination of red, green, sync (including both types), blue, and signal ground encapsulates the necessary components of an RGsB signal, ensuring all aspects of the signal are covered for effective transmission and display.

In contrast, other options either omit one of the critical components (like the blue channel for certain options) or do not specify the necessary sync components adequately, making them incomplete representations of the RGsB signal requirements.
