‘Dapog’ method of rice nursery was developed in

The correct answer is (d). The ‘Dapog’ method of rice nursery was developed in the Philippines. It is a method of rice nursery that uses a small amount of water and is less labor-intensive than traditional methods. The method involves growing rice seedlings in small containers, such as plastic bags or pots, and then transplanting them into the field when they are about two weeks old. The ‘Dapog’ method has been shown to be effective in increasing rice yields and reducing the use of water and pesticides.

The other options are incorrect. China, Indonesia, and Japan are all countries where rice is grown, but the ‘Dapog’ method was not developed in any of these countries.
