Solution

The correct option is A P is correct, Q is wrong
The aquatic floating plants are those that float on the surface of the water. These plants are spongy as they have empty spaces throughout their body in between the parenchymatous tissues (aerenchyma). These large intercellular spaces in the stem and root filled with air which help them to float. For example- Lotus is a floating aquatic plant of the Nymphaeaceae family. Thus the correct answer is option B.
