Answer 1

Answer: (A), (B)

The correct options are
A
The Earth is tilted on its axis.
B

Because the Earth revolves around the Sun.
The tilt of the Earth's axis is the most important reason why seasons occur. The Earth's movement around the Sun causes seasons. The Earth is always tilted to one side as it orbits the Sun. So, when the North pole tilts towards Sun, it's summer in the Northern hemisphere and winter in the Southern hemisphere.
