Best answer
The correct choice is (a) True

The best explanation: Yes, the secondary rainbow is fainter than the primary rainbow. As the secondary rainbow is formed by one more reflection than the primary rainbow, it is much fainter than the primary rainbow. The colors are also reversed in the secondary rainbow. In the primary rainbow, the violet color is on the inner edge and red color is on the outer edge. It is the other way round for the secondary rainbow.
