The correct answer is A) Tropical evergreen.
Tropical evergreen forests are the most common type of forest in Kerala. They are characterized by their dense canopy of trees that are always green. These forests are home to a wide variety of plants and animals, including many species that are found nowhere else in the world.
Deciduous forests are found in areas with a distinct wet and dry season. The trees in these forests lose their leaves during the dry season. Deciduous forests are not as common in Kerala as tropical evergreen forests.
Mangrove forests are found in coastal areas. The trees in these forests have adapted to live in salty water. Mangrove forests are important for protecting coastlines from erosion and for providing a habitat for many different species of plants and animals.
Alpine forests are found in high mountains. The trees in these forests are adapted to cold weather and low oxygen levels. Alpine forests are not found in Kerala.
