B. The distribution of sunlight.
C. The oceans' currents.
D. The prevailing winds.
The Earth has three main climate zones because of the differences in latitude and the distribution of sunlight.
Climate is the average weather conditions in an area for over a long period. Three major climate zones on Earth are:
1. Polar zone
The characteristic of this polar climate is cool summer and long extremely cold winter. The polar climate has a freezing climate and most of the time below zero degrees. The farther north of Canada, Europe, and Russia are the area that categorizes in this polar zone.
2. Temperate zone
The temperate climate zone lying between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year.
3. Tropical zone
The regions between the equator and the tropics are tropical zone. In this zone, the temperature is warm, has the most rain and little temperature variation. The climate is hotter here because the Sun’s light is directly overhead at the equator. An area in this zone has lush plants and trees and varied animals.

Explanation:
The body increases blood flow when it is exposed to the weakened or dead form of a pathogen.
The body raises its temperature when it is exposed to the weakened or dead form of a pathogen.
The body produces antibodies when it is exposed to the weakened or dead form of a pathogen.
Correct answer: D). The body produces antibodies when it is exposed to the weakened or dead form of a pathogen.
The vaccine consists of a weakened or dead pathogen, in response to that body produces antibodies after the administration of the first dose of vaccine. So, if the same body is exposed to that pathogen in the future the body will memorize it, and attack the pathogen more powerfully because it has already prepared an antibody against that pathogen in order to kill that foreign antigen.
Hence, the correct answer would be option D.
