B) draw the structure of ethane in line-bond mode. (do not draw the hydrogen atoms.)
2 answers:
There are two ways to represent the chemical formula of a substance: in condensed form or in structural form. Ethane is an alkane which consist of two carbon atoms. Since the general formula for ethane is CₓH₂ₓ₊₂, the condensed formula is C₂H₆. The structural formula or the line-bond structure is shown in the attached picture.

The substance that conducts electricity is dissolved in water.
So, option A is correct one.
When the sodium chloride dissolve in water , the sodium atoms and chlorine atoms separates under the presence of water molecules and exist as sodium cation and chloride anion . Now , they are free to move around in the water as positively and negatively charged ions . This separation of charge allows the solution to conduct electricity.
The solid and solid sugar does not conduct electricity because it is not dissolve in water . Similarly, sugar dissolved in water does not conduct electricity .
