The half-life of a radioisotope represent the time it takes for half of the material to decay to a daughter element (Option B)

This is the time taken for half a material to decay. The longer the half-life of an element, the more stable the element.

If the initial mass of an element is 100 g and after a particular time (say 72 minutes) the mass of the element is now 50 g.

Therefore, the time 72 minutes is called the half-life of the element because that is the time taken for half the element to decay.

With the above information in mind, we can conclude that the correct answer to the question is:

Option B. It represents the time it takes for half of the material to decay to a daughter element.
