Half-life for certain radioactive element is `5 min`. Four nuclei of that element are observed at a certain instant of time. After `5` minutes
STATEMENT-I: It can be definitely said that two nuclei will be left undecayed.
STATEMENT-II: After half-life that is `5` minutes, half of totan nuclei will disintegrate. So, only two nuclei will be left undecayed.

A

Statement-1 is True, Statement-2 is Ture, Statement-2 is correct explanation for Statement-1

B

Statement-1 is Ture, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is True, Statement -2 is False

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
