P450scc or cholesterol side chain cleavage enzyme is an enzyme that converts cholesterol into pregnenolone (the precursor for steroids). The kinds of steroid hormones are mineralocorticoids (i.e. aldosterone) glucocorticoids (i.e. cortisol), and sex steroids (i.e. testosterone, estrogen). In the event where P450scc is blocked, then there will be no production of mineralocorticoids, glucocorticoids, and sex steroids. There will be no production of aldosterone, cortisol, estradiol, testosterone, and progesterone. This disease is called Lipoid Congenital Adrenal Hyperplasia.

Habitat fragmentation is a process during which large habitat is fragmented in smaller habitats by man-made activities. Habitat fragmentation is a very harmful process as it is one of the major factors for the loss of biodiversity in the ecosystem.
Due to division of the larger habitat into the smaller fragments, the population present in the smaller area are more susceptible to extinction as they will not interbreed with the individuals of the population stuck in another small habitat.
Thus, Option-C is correct.
