The correct answer is (a).
The share of nuclear energy generated in India in the total energy generated was less than 3 percent in the year 2006-07. This is because India has a relatively small nuclear power program. As of 2020, India had 22 nuclear power reactors in operation, with a total installed capacity of 6,780 megawatts. This represents only about 3% of India’s total installed power capacity.
Option (b) is incorrect because the share of nuclear energy generated in India in the total energy generated was not between 3 and 4 percent in the year 2006-07.
Option (c) is incorrect because the share of nuclear energy generated in India in the total energy generated was not between 4 and 6 percent in the year 2006-07.
Option (d) is incorrect because the share of nuclear energy generated in India in the total energy generated was not between 6 and 8 percent in the year 2006-07.
