Correct Answer: Africa

Solution : The correct answer is Africa.

Tropic of Cancer, Tropic of Capricorn, and Equator all three pass from the African continent. Africa's longitudinal extent is 51 ⁰ E to 16 ⁰ W and its latitudinal extent is 37 ⁰ N to 35 ⁰ S. It is the second largest continent on earth and the only continent from which all the above 3 lines pass. The equator runs across Gabon, Congo, the Democratic Republic of the Congo, Uganda, Kenya, and Somalia in Africa.
