Question

The given table lists some of the fuels along with their calorific values and ignition temperatures in degree celcius.
$$\begin{array}{ccc}\text{Fuel}& \text{Calorific value (KJ/Kg)}& \text{Ignition temperature}\\ \text{A}& \text{200}& 50\\ \text{B}& \text{250}& 40\\ \text{C}& \text{100}& 70\\ \text{D}& \text{150}& 1000\end{array}$$
Which of the following is an ideal fuel?

• B. B
• C. C
• D. D
