Answer
The structure provided in option B represents a hydrocarbon with single bonds. The molecule can be identified as a saturated alkane, which follows the general formula for alkanes, C_nH_(2n+2). Here, counting the carbon atoms and hydrogen atoms confirms this structure.

Answer
The structure in option C depicts a hydrocarbon with double bonds between the carbon atoms, indicating that it is an alkene. The general formula for alkenes is C_nH_(2n). Thus, this structure represents a specific type of unsaturated hydrocarbon, which is distinguished by the presence of one or more double bonds. This affects its reactivity compared to saturated hydrocarbons.
