Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Multiplication factor, $k$ of a nuclear reactor is the number of neutrons in a generation of reaction per neutron in the previous generation.
For a chain reaction to sustain in critical condition, each generation must have one neutron per neutron in previous generation, i.e. $k = 1$ .
