(a)
Interpretation: The conversion of given ball-and-stick model of androsterone to a skeletal structure using wedges and dashed wedges around all stereogenic centers is to be stated.
Concept introduction: Steroids, a group of tetracyclic lipids composed of one five-membered ring and three six-membered rings. These rings are lettered by A, B, C, and D. Most of the steroids contain two angular methyl groups. These methyl groups are numbered as
