The correct answer is option 1, which states, "About 90 per cent of the area under pulses in India is rainfed." This means that the majority of the space used for growing pulses depends significantly on rain for irrigation, rather than human-made systems.

Options 2 through 4 are incorrect. Option 2 suggests that the share of pulses in the total cropped area in India has doubled in the last two decades. This is inaccurate as pulses cultivation has generally struggled to keep up with the pace of other crops. Option 3 states that India accounts for about 15 per cent of the total area used for rice cultivation worldwide, which is incorrect. Although India is a major rice producer, it does not contribute to such a high percentage of the global rice cultivation area. Option 4 suggests that Rice accounts for about 34 per cent of the gross cropped area in India, which is also misleading. Although rice is a key staple in India, it does not occupy such a high percentage of the cropped area.
