Thatching, coir production, and oil extraction are important economic activities related to:

Rubber
Coconut
Tea
Coffee Answer: b

The correct answer is: b) Coconut

Thatching, coir production, and oil extraction are important economic activities related to coconut.

  • Thatching is the process of covering a roof with thatch, which is a material made from plant fibers. Coconut leaves are often used for thatching, as they are strong and durable.
  • Coir is a fiber that is extracted from the husk of the coconut. It is used to make a variety of products, including rope, mats, and brushes.
  • Coconut oil is a vegetable oil that is extracted from the flesh of the coconut. It is used in cooking, cosmetics, and soaps.

Rubber, tea, and coffee are also important economic crops, but they are not as closely associated with thatching, coir production, and oil extraction as coconut is.
