Answer:
Option A. is the correct option.
Step-by-step explanation:
If a number is divisible by 5 it is not necessary that the number will be divisible by 10.
For example: 25 is the number divisible by 5 but not divisible by 10.
Or in other words a number divisible by 5 should be even to be divisible by 10.
So for the conditional statement : A number is divisible by 10 if and only if it is divisible by 5 will be false because any one out of these two statements is false. We know biconditional is true only when both the statements are true or false means both the statements should have same truth value.
Therefore Option A. is the correct option.
