    Answer:

    3.3\times 10^8\ btu/yr=11\ kW

    Explanation:

    Btu of British thermal unit is a unit of heat. The relation between btu/year and watts is given by :

    1\ btu/yr=3.343\times 10^{-5}\ W\\\\3.3\times 10^8\ btu/yr=3.343\times 10^{-5}\times 3.3\times 10^8\ W\\\\3.3\times 10^8\ btu/yr=11031.9\ W\\\\3.3\times 10^8\ btu/yr=11\ kW

    So,  3.3\times 10^8\ btu/yr is equal to 11 kW. Hence, the correct option is (d).
