oa. positron emission
ob. gamma decay
oc. nuclear fission
od. nuclear fusion

C. Nuclear fission

Explanation:

Nuclear fission is the reaction in which the nucleus of a heavy atom, when bombarded with neutrons (or when capturing an incident neutron), becomes unstable and divides into two or more nuclei of lighter atoms, giving rise to a situation of greater stability. In this process that takes place in the atomic nucleus, neutrons, gamma rays and large amounts of energy are emitted.  

Then, with this division a great release of energy occurs and the emission of two or three neutrons, other particles and gamma rays.  

This means fission is a process in which energy is released by the separation of the components of the nucleous of the atom.

In other words:

Matter is converted to energy, and in the case of powew plants, in electric energy.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
