The correct answer is - d. At the last glacial maximum, sea level was about 100 meters (300 feet) lower than it is today.
The sea level has always been changing, it has been increasing when the climate has been warmer, and it has been decreasing when the climate has been lower.
During the last glacial period's maximum, which was around 20,000 years ago, the sea level was little more than 100 meters lower than what it is now, some estimates suggest around 120 meters lower. This low sea level enabled lot of places to be connected, like Asia and North America, the islands of Southeast Asia were a single land, the British Isles were merged with Europe, and that helped a lot in the migration of the animals, but also the humans.
The reason for such low sea levels in the glacial periods is that large portion of the ocean waters get frozen at the higher latitudes, thus extracting the water from the oceans and concentrating it as ice further north and south.
It does on its western side. On its other sides it belongs to Chile, Peru, Bolivia and Argentina.

Explanation:
The major rocks of Earth's crust are classified into three principal types based on their origin and appearance. Rocks in pure terms of geology can be defined as naturally occurring and coherent aggregate of one or more minerals.
Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These three classes are-
- Igneous Rocks: Igneous rocks are those which have been formed from molten lava
- Sedimentary Rocks: Sedimentary rocks consists of fragments derived from preexisting rocks or of materials precipitated from solutions.
- Metamorphic Rocks: Metamorphic rocks are those that have been derived from either igneous or sedimentary rocks under conditions that caused changes naturally and over time.
