Explanation:

Let's explain each statement with Koeppen's classification:

- (A) Cwg - Bharatpur:

Cwg signifies a warm temperate climate with dry winters (subtropical, with dry winter). Bharatpur in eastern Rajasthan fits this.

- (B) Bwhw - Barmer:

Bwhw means hot desert climate (arid, dry, hot throughout). Barmer, in western Rajasthan, is indeed a hot desert.

Bshw is semi-arid, hot steppe climate. Ganganagar, in the north-west, has this steppe (semi-arid) climate.
