Solution

The correct option is B Molybdenum oxide

Alkanes on heating with a regulated supply of dioxygen or air at high pressure and in the presence of suitable catalysts give a variety of oxidation products. This process is called controlled oxidation.

O2+CH3CH2CH3Mo2O3−−−ΔCH3CH2CHO

Mn(OAc)2-manganese acetate oxidise alkanes to carboxylic acids in presence of O2 and heat.
Cu at high temperature and pressure oxidise alkane to alcohol.
Alkanes does not reacts with KMnO4.

Hence, option (c) is correct.
