Characteristics of two fuels X and Y are given in chart.
| Characteristics | Fuel X | Fuel Y |
| Calorific value | 50 kJ/g | 80 kJ/g |
| Gases produced on burning | CO, SO2 | CO2 |
| lgnition temperature | 20°c | 80°c |
Which fuel is ideal fuel?
(A) Fuel X, because it has lower ignition temperature and lower calorific value.
(B) Fuel Y, because it has higher ignition temperature and lower calorific value.
(C) Fuel X, because it has lower ignition temperature and is producing CO, and SO2.
(D) Fuel Y, because it has higher calorific value and is Producing only CO2.
