Explanation:

Option 1 is not correct: Tidal energy uses the periodic rise and fall of waters of the ocean for generation of electricity and not run of the river system.
Option 2 is correct: Small-scale hydro project: The flow of river water is harnessed by channelising it through a narrow canal without any creation of artificial reservoir, this type of system is called as 'run of the river systems'. It produces small amount of electricity which can be utilized on a small scale.
Option 3 is not correct: Large reservoir based hydro project: It involves creation of artificial reservoir of water to produce a huge amount of electricity. Run-of-river systems do not rely on large storage reservoirs, but rather on the diverted river water to drive turbines, and then discharge the water back into the river system.
