The question provides three statements regarding seabed exploration and mining in international waters, and the task is to identify the correct ones.

1. The first statement states the Global Ocean Commission grants licenses for seabed exploration and mining in international waters. This statement is incorrect because the International Seabed Authority, not the Global Ocean Commission, is the organization responsible for regulating these activities.

2. The second statement asserts that India has received licenses for seabed mineral exploration in international waters. This statement is accurate. India holds licenses to explore areas of the deep seabed in international waters for strategic mineral deposits.

3. The third statement, stating that `rare earth minerals` are present on the seafloor in international waters, is also true. The seabed in international waters is often rich in these minerals, such as polymetallic nodules, cobalt-rich crusts, and polymetallic sulfides.

Hence, the correct answer is option 2, `2 and 3 only,` as these two statements are accurate and the first statement is incorrect.
