I'll give brainliest if it is correct or you give a good explanation

Answer:
Position 2
Explanation:
Since it is on the Tropic of Capricorn, for it to be exactly on top of Africa, it must be in position 2. The Tropic of Capricorn is special because the sun is directly on top of it when the south part of the Earth is facing the sun, like position 2. Position 1 and 3 are directly at the Equator because neither part is tilted towards or away from the sun. Position 4 is directly above Tropic of Cancer. The Tropic of Cancer, like the Tropic of Capricorn, has the sun directly on top of it when the north part of the Earth is tilted towards the Sun.
I hope this helps!!! :)
