The correct option is: 2. Propane

Explanation:

Minimum ignition energy, abbreviated as MIE, is the minimum energy required to ignite the flammable mixture of air at atmospheric pressure and room temperature. The unit used to measure this energy is millijoule, mJ

The values of the minimum ignition energy for the following gases are:

Butane = 0.25 mJ

Propane = 0.26 mJ

Ethylene = 0.07 mJ

Hydrogen = 0.017 mJ

Cyclohexane = 0.22 mJ

Therefore, among the following gases, Propane requires the most ignition energy, 0.26 mJ.
