If we guide ourselves with the Moh´s scale:
Material scratches apatite → material is harder than 5.
Material is scratched by corundum → material is softer than 9.
Conclusion:
The hardness of the unknown material stands between 5 and 9.
Note:
Both apatite and corundum are defining materials (reference materials in the Moh´s scale). So, you can also give an answer using defining materials:
"It can either be an orthoclase feldspar, a quartz or a topaz".

Correct answer: C). Oxidative phosphorylation
Oxidative phosphorylation gives a basic unit of energy for all the metabolic processes called as ATP, it is a highly efficient metabolic process which is known to produce a large amount of ATP.
During the process of oxidative phosphorylation, electrons are exchanged between the molecules, that creates a chemical gradient, which is required for the production of ATP. It is known to produce more ATP called the energy currency of cell that any other cellular respiration. It produces 90% of the total ATP synthesized in the cell.
