Solution

The correct option is A Cross hybridisation
The products of cross-hybridization (hybrid plants) are usually more vigorous and faster growing than other plants, they are disease resistant, stress-resistant etc, thus, by doing cross-hybridization in plant breeding, the average production of crops improved which leads to Green Revolution. Thus, the correct answer is 'Cross hybridization'.
