The correct answer is C. mesophytes.
Mesophytes are plants that grow in environments with average levels of moisture and temperature. They are the most common type of plant, and they can be found in a variety of habitats, including forests, grasslands, and deserts.
Halophytes are plants that grow in salty environments, such as salt marshes and coastal areas. They have special adaptations that allow them to tolerate high levels of salt, such as thick, waxy leaves that help to prevent water loss.
Hydrophytes are plants that grow in water, such as in ponds, lakes, and rivers. They have special adaptations that allow them to survive in aquatic environments, such as long, thin leaves that help them to absorb nutrients from the water.
Xerophytes are plants that grow in dry environments, such as deserts. They have special adaptations that allow them to conserve water, such as thick, waxy leaves and deep roots.
