Below are two statements given, where one is a statement

Solution

• Statement (A) talks about how human population increases on the banks of the Ganga when it moves east and west. This is because rivers, especially the Ganga, have traditionally been the focal points of human settlement due to their role in irrigation, transportation, and providing fresh water. • Reason (R) explains that when the Ganga flows east and west, it increases in height, which results in more human settlements and water flowing into the river. This is a correct cause as increased water flow typically promotes settlements near rivers. Since both statements are correct, and R provides the explanation for A, the correct answer is (a).
