Unsaturated hydrocarbons have a higher density than saturated hydrocarbons. D. Thicker oils are more solid than liquid, so they have another phase change to complete

    you know that B is not "always" true, so why would C be relevant?

    One possible explanation could be that saturated hydrocarbons don't have a any double bonds, so their structure allows them to stack and those interactions could contribute to a higher MP/BP Unsaturated because they contain double bonds don't have this interaction.

    I would argue that it's due to intermolecular attraction, if you have compounds like glycerol. But generally these are a mixture of compounds so they have more polar compounds attracting to each other, making it more viscous.
