Wind is an inexhaustible source of energy and an aero-generator can convert it into electricity. Though not much has so far been done in this field, the survey shows that there is a vast potential for developing wind as an alternative source of energy. The wind survey has four components - direction, duration, speed and distribution. On this basis U.P. hill areas have been found an ideal place for setting up aerogenerators. In U.P. hills alone, as many as 58 sites have been identified.
The survey was conducted under the government of U.P.?

Correct option is A

While the passage provides information about the survey identifying 58 suitable sites in the U.P. hill areas for setting up aero-generators,
it does not specify who conducted the survey or whether it was under the government of U.P. This information is not explicitly stated.​​
So, data inadequate.
Thus, the correct answer is (a).
