The diagrams, labeled A, B, and C, represent equal-sized portions of the Sun’s rays striking Earth’s surface at 23.5° N latitude at noon at three different times of the year. The angle at which the Sun’s rays hit Earth’s surface and the relative areas of Earth’s surface receiving the rays at the three different angles of insolation are shown. As viewed in sequence from A to B to C, these diagrams represent which months and which change in the intensity of insolation?

• December → March → June; and decreasing intensity

• December → March → June; and increasing intensity

• June → September → December; and decreasing intensity

• June → September → December; and increasing intensity
