Both photosynthesis and photovoltaic cells need light in order to produce energy, though photosynthesis does have a process that can occur in the absence of light, so option C is correct.
Photovoltaic cells are man-made panels that use solar light to create energy. They do this by taking advantage of the natural ability of some materials to absorb the photons in sunlight and use them to release electrons. The release of electrons generates an electric current which produces energy.
Meanwhile, photosynthesis is a naturally occurring process by which plants and a handful of other organisms produce energy. Photosynthesis also requires the presence of sunlight to function. However, photosynthesis also has a dark phase where the chemical reactions continue despite the absence of light. For these reasons, option C is correct whilst the rest are false.
