Final answer:
Cycloheptane is comprised of seven carbon atoms forming a ring, which corresponds to a 7-sided polygon. The correct answer is options A.
Step-by-step explanation:
The name cycloheptane indicates a cyclic (cyclo) alkane with seven (hept-) carbon atoms. It can be represented as a seven-sided polygon. To select the structure corresponding to cycloheptane, one must understand the basic nomenclature of cyclic hydrocarbons in organic chemistry.
The prefix 'cyclo-' indicates that the molecule forms a ring, and the 'heptane' part signifies that there are seven carbon atoms present in the molecule. Therefore, the correct structure for cycloheptane is a 7-sided polygon.
