Identify the incorrect statement from the following:

Explanation

Option A is true: iso-paraffins crack faster than n-paraffins. Option B is incorrect because catalytic cracking is an endothermic process, meaning it requires heat input, while catalyst regeneration is exothermic, releasing heat. Option C is accurate: olefin decomposition proceeds slightly slower in catalytic cracking than in thermal cracking. Option D is incorrect since there is a wrong statement present.
