Question : The fuel that is used in modern submarines is
Option 1: Nuclear fuel
Option 2: Petrol
Option 3: Coal
Option 4: Diesel
Correct Answer: Nuclear fuel
Solution : The correct option is - Nuclear fuel
Modern submarines typically use nuclear reactors as their primary source of power, which allows them to operate for extended periods of time without the need to surface frequently for refueling. These nuclear reactors use enriched uranium or plutonium as fuel to generate heat through nuclear fission. The heat produced by the fission reactions is used to produce steam, which drives turbines connected to generators to produce electricity for propulsion and onboard systems.
