The correct answer is: A. Time of maximum solar radiation and the time of maximum temperature.
The lag in daily temperature refers to the time lag between the time of maximum solar radiation and the time of maximum temperature. This is because it takes time for the Earth’s surface to heat up and cool down. The lag is typically about 2 hours, but it can vary depending on the time of year and the location.
Option B is incorrect because the time of minimum temperature is typically before the time of maximum solar radiation.
Option C is incorrect because the minimum and maximum temperature for a day can occur at any time of day.
Option D is incorrect because the minimum and maximum solar energy received at the surface for a given day can occur at any time of day.
Option E is incorrect because sunrise and sunset do not necessarily coincide with the time of maximum or minimum solar radiation.
