The correct answer is: A. Upward
In the figure below, energy is being transported upward from the sun to the Earth. This is because the sun is a star, and stars produce energy through nuclear fusion. Nuclear fusion is a process in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as the release of large amounts of energy.
The energy produced by nuclear fusion in the sun is released in the form of electromagnetic radiation, including visible light. This light travels through space and reaches the Earth, where it is absorbed by plants and other organisms. The energy from the sun is then used by these organisms to produce food.
The food that is produced by plants and other organisms is then eaten by animals, including humans. The energy from the sun is then used by animals to power their bodies.
In this way, energy from the sun is transported from the sun to the Earth and then to all living things on Earth.
Option B is incorrect because energy is not being transported downward in the figure.
