Question

Which of the following property is not a characteristic of a good fuel?

• A. High ignition temperature
• B. Low cost
• C. Causes minimum pollution
• D. Readily available

Answer 1

The correct option is A High ignition temperature

The fuel that has low cost causes minimum pollution, and is readily available, is a good fuel.

But, when we consider the ignition temperature of the fuel, it should not be too high nor too low. The fuel with a low ignition temperature easily catches fire and is unsafe. On the other hand, the one with a high ignition temperature does not readily catch fire and is difficult to use. So option A is the correct one.
