The correct option is (a) Koyna dam

To elaborate: A very strange phenomenon has been observed in several dams of the world, the reservoir basins which were seismologically inactive started showing seismic activities when the reservoir was filled up with water. Koyna dam (Maharashtra) is an important example of such a case.
