The correct answer is A. Advection.
Advection is the transport of heat, momentum, and other properties of a fluid (a substance that can flow, such as a gas or liquid) due to the bulk motion of the fluid itself. In meteorology, advection is the transport of heat, moisture, and momentum by the wind.
Radiation is the transfer of energy by electromagnetic waves. The sun radiates energy to the Earth, and the Earth radiates energy back to space. This process is called the greenhouse effect.
Conduction is the transfer of heat between two objects that are in direct contact with each other. For example, when you touch a hot stove, the heat from the stove is transferred to your hand through conduction.
Latent heat is the heat that is absorbed or released when a substance changes state, such as from a liquid to a gas or vice versa. For example, when water evaporates, it absorbs heat from the surrounding air.
Reflection is the bouncing of light or other waves off of a surface. For example, when you look in a mirror, you see a reflection of yourself.
