What is a correct description of an LP cyclone’s impact?

Explanation:
A low-pressure cyclone creates a strong horizontal pressure gradient at the surface, which drives high wind speeds around the center. Those winds transfer energy to the sea, producing rough to high seas with heavy spray. This combination—strong winds and high seas—is the hallmark impact for an LP cyclone. The other statements don’t fit: wind and seas are not light or calm; cyclones move rather than remaining stationary; and surface pressure tends to fall or stay low as the system intensifies, not rise rapidly.
