Identify the incorrect statement regarding gas turbines:

Explanation

Option A is false because gas turbines generally require external means, such as an electric motor or compressed air, to start and are not self-starting units. The other statements are true: gas turbines use less water than steam plants, have high exhaust losses due to large mass flow, have lower overall efficiency compared to reciprocating engines, and can be easily started and stopped, which suits them for peak load operations.
