• B. epiphytes
• C. xerophytes
• D. mesophytes

Answer 1

The correct option is C

xerophytes

The correct option is C

Explanation of correct option-

1. Xerophytes are the plants that grow under very poor water condition such as deserts are called xerophytes.
2. That is the reason they have sunken stomata to reduce the amount of water loss by transpiration

Explanation of incorrect option

Option A

1. Hydrophytes are aquatic plants and they recieve more amount of water.
2. So the floating hydrophytes have broad leaves and larger number of stomata on the upper surface but the submerged hydrophytes lack stomata.

Option B

1. Epiphytes are air plants.
2. Epiphytes derive nutrients from the dead and decaying plant parts present around the surface.

Option D

1. In mesophytes, stomata are generally found on the under surface of the leaves, water evaporates upwards, having the majority of stomata on the underside of the leaf will mean water is trapped under the leaf, which reduces water loss.

Final answer: Sunken stomata are present in Xerophytes.
