The correct answer is A. Temperate cyclones (also known as extra-tropical cyclones or mid-latitude cyclones) typically move from west to east under the influence of the prevailing westerlies in the mid-latitudes. Tropical cyclones (like hurricanes and typhoons) form over warm tropical oceans and are generally steered by the trade winds, which move from east to west in the tropics.

Temperate cyclones follow westerlies (west to east), while tropical cyclones generally follow trade winds (east to west).

Tropical cyclones are characterized by a distinct “eye,” a central region of clear skies and calm winds, which is not the ‘front side’. Both temperate and tropical cyclones are low-pressure systems, with lowest pressure at the center. Hurricanes are tropical cyclones, not mid-latitude phenomena.
