Each nucleotide is made up of three subunits as:

1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.

2. Phosphate group (PO₄³⁻)

3. Nitrogenous bases: adenine, guanine, adenine and cytosine.

Thus, ribose is the correct answer.

Explanation:

Stomata are the small structure resemble as tiny or pinholes that found on the underside of the leaves and play many roles in the plant. Stomata help in the gas exchange and also helps in transpiration.  It allows oxygen a gas and water in vapor form from the leaves to the outer environment and let carbon dioxide inside the cell.

This system also helps in transpiration by closing and opening stomata with the help of their guard cell by becoming turgid and flaccid by osmotic pressure.
