The rays of sunlight that are moving straight from the sun and are perpendicular to the surface of the Earth are called direct rays. To determine the correct answer, you would need to understand the concept of direct rays and their relationship with the position of the sun and the Earth's surface. Direct rays occur when the angle of the sun's rays is 90 degrees with respect to the Earth's surface. This typically happens during the equinoxes when the sun is directly above the Earth's equator. By understanding this concept, you can conclude that the correct answer is "direct rays."
