D)low number density n and low temperature T
E)high number density n and temperature T = 0 K

Question

Quizplus · Accepted Answer

In a controlled nuclear fusion reaction, high number density of reactants is required to increase the likelihood of collisions between the nuclei. Additionally, high temperature is required to provide enough kinetic energy for the nuclei to overcome their electrostatic repulsion and merge together in a fusion reaction. Therefore, the best choice is high number density n and high temperature T, which is option A.
