What effect occurs when you increase the threshold control?

Explanation:
Raising the threshold control changes what the display shows by setting a minimum signal level that must be met to be displayed. Echoes weaker than that level are filtered out, so increasing the threshold makes weak echoes disappear from the image. Strong echoes, which exceed the threshold, remain visible, so you can still see bright interfaces while faint details fade away. This is why the correct effect is a decreased appearance of weak echo signals.
