Best answer
Correct choice is (c) High Temperature and High Pressure

Easy explanation: The fusion reaction takes place under the conditions of extremely high temperature (≈ 10^7 K) and pressure. This is necessary so that the protons have high enough Kinetic Energy to overcome their mutual repulsion.
