1990
In 1990, the world population was 2000 million. Thus, a is 2000.

1947
In 1947, the population of India was 350 million and the world population was 2600 million. Thus b is 350.

2000
In 2000, the population of India was 1000 million and the world population was 6000 million. Thus, c is 1000 and d is 6000.

2011
In 2011, the population of India was 1200 million and the world population was 7200 million. Thus, e is 1200 and f is 7200.

Final answer
(C) a - 2000, b - 350, c - 1000, d - 6000, e - 1200, f - 7200
