The mechanism of heat transfer involved in heat flow from Sun to Earth is radiation. So, the correct answer is a. radiation.

Here's why:

1. Radiation is the transfer of heat through electromagnetic waves. It doesn't require a medium (like air, water, or metal) to move through, which is why it can travel through the vacuum of space from the Sun to the Earth.

2. Convection is the transfer of heat through a fluid (like air or water) where the warmer part of the fluid rises and the cooler part sinks. This can't be the answer because space is a vacuum, not a fluid.

3. Induction is a method of transferring heat through an electrical or magnetic field, which is not applicable in this case.

4. Conduction is the transfer of heat through direct contact of particles, which also can't be the answer because space is a vacuum, so there's no direct contact between the Sun and the Earth.

5. "None of these" is not the answer because radiation, one of the options, is the correct answer.
