Model Answer

(a) Both A and R are true, and R is the correct explanation of A.

The Konkan Railway has faced problems of track sinking and landslides because the western coastal region has difficult terrain with heavy rainfall and unstable slopes.

Source: Railways, Chapter 7

Explanation

The textbook directly states that Konkan Railway "has also faced a number of problems such as sinking of track in some stretches and landslides." The western coast (Sahyadri/Western Ghats region) is known for heavy rainfall and steep, unstable slopes — this terrain is the direct cause of those problems. So R correctly and logically explains A, making option (a) the right choice.
