Correct Answer - Option 2 : 1200 kW

**Concept:**

The efficiency of the turbine is given by;

\(η_T =\frac{Output\ Power}{Input\ Power}\)

**Calculation:**

**Given:**

η_{T} = 25% = 0.25, Output Power = 300 kW

\(0.25 =\frac{300}{Input\ Power}\)

\(Input\ Power =\frac{300}{0.25}\)

**Input Power = 1200 kW**
