I know for a fact c is one of the correct answers and I also think b is the other correct one
The axis of the earth is tilted (ANSWER IS C). The equator is heated more than other areas because the sun's rays hit it directly.
As you move north or south of the equator, they fall slantingly or obliquely.
When summer is in the south and vice versa, the heat also changes with the earth's rotation.
The tropic of Capricorn and the tropic of Cancer alternately get direct sunlight.
Due to the uneven heating of the earth, wind and ocean currents are created, supporting life.
Consequently plant roots will get more moisture with less effort. It also improves soil structure due to alternate drying and cooling and soil aeration which helps in multiplication of micro-organisms. This is the reason that farmers plough their field during summer. These are reasons why farmers plough their fields during the summer.
Hope this helps! :3
