Solution

The correct option is B Hydrogen peroxide
$H_{2} O_{2}$ burns without the need for an outside air supply. So, it is used with oil as an under water fuel as when $H_{2} O_{2}$ is injected into a reservoir sand, it decomposes slowly giving off heat and $O_{2}$ . The liberated $O_{2}$ reacts with residual oil generating more heat and ${C O}_{2}$ .
