Question

at position 3, which latitude is receiving the most direct sunlight? (highest angle of incidence) tropic of cancer tropic of capricorn south pole equator

Explanation:

When the Earth is at position 3, it is the winter solstice in the Northern Hemisphere. During this time, the Sun is directly overhead at the Tropic of Capricorn ($23.5^{\circ}\text{S}$). This means that the Tropic of Capricorn receives the most direct sunlight (highest angle of incidence) at this position. The Tropic of Cancer ($23.5^{\circ}\text{N}$) would have the most direct sunlight during the summer solstice (position 1). The South Pole has 24 - hour daylight but not the most direct sunlight in terms of angle compared to the Tropic of Capricorn at this position. The Equator has relatively even sunlight throughout the year but not the most direct at position 3.

Answer:

Tropic of Capricorn
