Detailed Explanation:

Amarkosha is a Sanskrit lexicon compiled by Amarasimha that classifies land types based on physical and agricultural characteristics.

✅ Statement a – Correct: Urvara refers to fertile land suitable for cultivation.

✅ Statement b – Correct: Maru denotes desert or barren land.

✅ Statement c – Correct: Shadvala means grassy land or pasture land.

✅ Statement d – Correct: Devamritaka refers to land watered by rain (rain-fed land).

All four statements are correctly matched. Since Option 1 (a and b), Option 2 (c and d), and Option 3 (b, c, and d) are individually correct, the answer is Option 4 – More than one of the above.
