Explanation:

Let us calculate the yield for the crops given in the options for the year 2006:
Castor Seed = 135/106 ≈ 1.27
Groundnut = 491/317 ≈ 1.55
Maize = 1102/1004 ≈ 1.1
Sunflower = 880/472 ≈ 1.86
Rice = 153/107 ≈ 1.43
Bajra = 2172/4992 ≈ 0.43
The top three crops by yield are Sunflower, Groundnut and Rice.
Hence, option (b).
