d.

a. True

b. False

Option B) False

Explanation:

Vitamin D, particularly known as cholecalciferol is formed when an individual is exposed to sunlight, such that the ultraviolet (UV) component of the sunlight activate the 7-dehydrocalciferol (the vitamin D precursor) to undergo hydroxylation and yield 1,25-dihydroxycholecalciferol (active vitamin D)

Thus, the formation of vitamin D is neither difficult in dark skinned individuals nor light skinned individuals. So, the statement is false.
