Solution

The correct option is A $\frac{Q_{H}}{Q_{T}}$
Solution: The ratio of the work done by the engine to the heat supplied to the engine is called thermal efficiency. It s given by,
$η_{T} = \frac{Q_{o u t}}{Q_{i n}}$
where, W is the work done and H is the heat supplied to the engine.
Hence, the correct option is (A).
