Answer:
Option (C)
Explanation:
A nuclear power plant is considered to be a thermal power station where the main source of heat is the nuclear reactor. Here, energy is released in the form of heat that helps in generating steam. This steam then initiates the motion of the turbines that are connected to a generator. These turbines when rotates produce electricity.
These nuclear plants are less costly and they do not emit any kind of pollution. They are very efficient to use but has certain disadvantage, that the waste materials it releases contain some amount of radioactive element in them and are difficult to dump.
Thus, the turbines in a nuclear power plant is turned on by the steam.
Hence, the correct answer is option (C).
