The correct answer is C.

This area shows a convergence of northeast winds in the north, with southwest winds in the south. This coincides with a dense, continuous cloud mass and most likely corresponds to a front (a meteorological feature).

Ambiguity in wind direction is usually 180 degrees. It tends to be greater in areas of lighter wind and in areas of convergence or divergence over distances of less than several hundred kilometers.

Rain-contaminated wind vectors usually line up perpendicular to the satellite’s motion. They tend to lead to a higher wind speeds and loss of directional information.
