Answer : The correct answer is -

c. the size of the stomata.

Guard cells are the specialized cells, which are present around stomata (tiny holes/openings on the leaves) in plants.

These cells regulate the opening and closing of stomata, which help in the exchange of gases and loss of water in the atmosphere that is transpiration.

Thus, it can be concluded that guard cells help in controlling the size of stomata.

<h3>What is Genotype?</h3>

An organism's genotype is made up of all of its genetic components. The alleles or variations that a person holds in a specific gene or genetic region are also referred to as the genotype.

The amount of copies of each chromosomes found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two different alleles for each gene. Homozygous refers to a genotype where both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.

Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.
