A wooden block, with a coin placed on its top, floats in water as shown in figure. The distance l and h are shown here. After some time the coin falls into water. Then

A

`l` decreases and `h` increases

B

`l` increases and `h` decreases

C

both `l` and `h` increases

D

both `l` and `h` decrease
