Solution
The correct option is B cyclo The parts of the name that precede the root word are called prefixes. For example, in the compound, cyclobutane, cyclo is the prefix that indicates the alicyclic nature of the compounds. A primary prefix is used to differentiate acyclic and cyclic compounds. But the rules for using these are slightly different. Ex: In cyclic compounds, the prefix cyclo is added before the word root.
