4. Ramganga	Multipurpose project

A. 2, 3 and 4
B. 1, 2, 3 and 4
C. 3 and 4
D. 1 and 2

Answer 1

Hint:It is situated in Kerala. It is a unique dam in India as well as Asia. It is an arch dam.

Complete answer:
India is a country with numerous rivers with many of them being perennial rivers. Due to this, it has a lot of river valley projects on many of the major rivers in the country. Most of the projects serve more than a single purpose. They are constructed for many reasons like hydroelectricity, water supply, irrigation etc. Let us now take a look at the given options to see which of them are correct.
1. The Idukki dam is built over the Periyar river in Kerala. This dam was constructed for the sole purpose of generating electric power. So, it is a hydro-electric project and not a thermal power plant. This is incorrectly matched.
2. Sabarigiri dam is located on the Pamba river in Kerala. It is a hydro-electric project which is controlled by the electricity board of Kerala. So, this option is correctly matched.
3. Ghatprabha is an irrigation project. On the left bank of the river Ghatprapha is the network of canals that supply water for irrigation. Thus, this is correctly matched.
4. The Ramganga dam is built on the river of the same name in the state of Uttarakhand. It is both an irrigation and a hydro electric project, making it a multipurpose project. Therefore, this too is correctly matched.

Hence, Option A is the correct answer.

Note:Idukki dam is an arch dam with a parabolic, double curvature. It is also the highest arch dam in Asia.
The Sabarigiri power station is the second largest station for generation of hydro electricity in Kerala.
Ghataprabha river irrigation project is also a part of the Hidkal Dam.
The Ramganga dam provides irrigation water to 57,500 ha (142,086 acres) of farmland.
