Answer» CORRECT choice is (a) CRITICAL size Explanation: If more than one of the neutrons produced in the fission of uranium 235 is capable of inducing a fission reaction, then the number of fissions taking place at successive stages goes increasing at a very brisk rate and this generates a series of fission reactions. This is known as a chain reaction. If the mass of the Uranium235 sample is greater than a CERTAIN size called the critical size then it is capable of CONTINUOUS fission by itself. So, X is critical size.
