A gas water heater is 75% efficient. The energy output used to heat the water is 4.6 kWh.then the energy input is 6.1  kWh

What is the efficiency of an engine?

The efficiency of an Indian can be defined as the ratio of the total useful work done by the engine to the total heat absorbed by the engine

It can be represented in the form of percentages or in terms of fractions as well.

In general, the efficiency of an engine is represented by the greek symbol η.

Efficiency = output heat  /input heat

η = output heat /input heat

0.75  = 4.6 kWh /input heat

energy input = 6.1  kWh

Thus, the energy input is 6.1  kWh, therefore the correct answer is option C
