Solution

The correct option is B False
This statement is false because half life period is defined as the time during which half the amount of a given sample of the radioactive substance disintegrates.
Since half life period of the element is 8 hours, it is not possible for the element to reduce to 1/4 after two hours. It would take 16 hours (2 half lifes) for the element to reduce to 1/4 of the initial number
