How to do ?
Dear Student,
Increased branching results in a higher heat of combustion. Branched alkanes are thermodynamically more stable than the linear ones. (They have the lower surface area and a more compact structure, which increases its stability and lowers its energy)
Now stability is directly proportional to the heat of combustion. More stable is the compound, more heat energy would be released upon its combustion (as more energy would be required to decompose it).
Hence, option C is the correct answer (As it has most branching and thus releases maximum energy of combustion)
