Given data:

\mathrm{ T_h=800 \mathrm{~K} }

\mathrm{ T_c=300 \mathrm{~K}}

The efficiency of a Carnot engine is given by:

\mathrm{ \text { Efficiency }=1-\frac{T_c}{T_h} }

Plugging in the values:

\mathrm{ \text { Efficiency } = 1 -\frac{300 K }{800 K} }

\mathrm{\text{Efficiency=0.625}}

Therefore, the correct option is 1
