Solution

The correct option is A 3.7 billion years ago
The primitive ocean-covered Earth was disrupted by molten rock that burst through the Earth’s crust and rose up to the ocean surface as lava. Over time, the lava cooled, forming volcanic islands. These islands joined to form the first continents. About 3.7 billion years ago the first microscopic organisms existed in the oceans of Earth.
