The sugar is b. A compound.

• A compound is formed by the chemical combination of two or more elements that cannot be separated into its constituents by physical methods. Only chemical methods convert them into their constituents.
• Sugar is a compound as when it is heated it oxidises and is changed into black coloured carbon and water. Hence, it is made up of two or more elements.
• Sugar is not an element as an element contains only one type of atom.
• A mixture is formed by the physical mixing of substances while a solution is formed when a substance dissolves into another substance. Hence, sugar is not a mixture and solution.
