Weight of five bats B1, B2, B3, B4 and B5 is compared. Weight of B4 is more than B1 and less than B2. Weight of B5 is more than B3. Weight of B2 is less than B3. Whose weight is more than B4 but less than B3?

I. B2

II. В1

Weight of five bats B1, B2, B3, B4 and B5 is compared. 

Weight of B4 is more than B1 and less than B2.

Weight of B5 is more than B3.

Weight of B2 is less than B3.

B1 < B4 < B2 < B3 < B5

​So, B2 is the one whose weight is more than B4 but less than B3

Thus, the correct option is: (a) Only I​​
