Answer: B
Explanation: Factors affecting surface temperature of oceans are:
Latitude: Surface temperature of sea water is mostly increases close to equator and diminishes as one moves towards posts.
Prevailing Winds: Coriolis power causes the exchange winds to move from east to west on the two sides of the equator. Winds convey with them the warm surface water from eastern sides of the seas to western side. Because of this the surface temperature of seas on the eastern parts is a lot of lower than that on western parts.
Salinity: Saline water absorbs more heat than fresh water.
Adjoining land masses–Temperature of encased oceans rises and falls rapidly because of warmth move from land to oceans and the other way around.
