If a question mentions Sahyadri, with what should it be identified?

Correct answer: Western Ghats

Sahyadri is the traditional name commonly used for the Western Ghats, the mountain chain running along the western edge of Peninsular India. Thus, when a textbook or question uses Sahyadri, it is referring to the same major physical feature as the Western Ghats. Recognising alternative names is useful because geography questions may use either term.

The Western Ghats lie roughly parallel to the western coast and form an important highland boundary of the peninsula. The Eastern Ghats are a different, more discontinuous range on the eastern side. The Aravallis are an older range in northwestern India, while Himadri is the highest Himalayan division. Therefore option A is correct: Sahyadri and Western Ghats identify the same range in this context.
