The correct option which represents the point in Earth's revolution around the Sun when it is at aphelion is A. in early July.
Aphelion is a term which means 'farthest from the Sun,' which for Earth is around July 4th. Even though it seems weird, because you'd think it's cold when the Earth is so far away from the Sun, because the Earth's axis is tilted, everything is reversed - it is hot when it is farther from the Sun, and cold when it is closer to the Sun.
