Please select the best answer from the choices provided.

The correct answer is letter C

The equatorial climate is found in the regions of low latitudes, that is, as the name implies, in the vicinity of the parallel of Ecuador. It is a very specific climate and has unique characteristics. This specificity contributes to the exuberant Equatorial Forest in this climatic type.

One of the most striking characteristics of this type of climate is the high temperatures throughout the year. The annual average fluctuates around 27 ° C. Temperatures are high due to the latitude of the region. In the equatorial region, the sun's rays strike perpendicularly, which causes temperatures to rise year-round.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.

i think it is the third one.
