The correct answer is: If both assertion and reason are true but assertion is not a correct explanation of the assertion.
A quasar is a very big source of radio waves and its size is very small as compared to the size of a galaxy. A radio galaxy emits radio waves which lie in the range $10^{30}$ to $10^{38}$ watt. A quasar emits radio waves which lie in the range of $10^{37}$ to $10^{38}$ watt.
