    Answer:

    a) water expands when it freezes and damages the cell wall.

    Explanation:

    We know that most liquids expand when heated and contract when cooled. Water does not behave in the same way.

    Water contracts on cooling from any temperature until 4°C when it begins to expand until 0°C. Hence a given mass of water has its least volume and highest density at 4°C.

    Hence, fresh vegetables with high water content do not freeze well because water expands when it freezes and damages the cell wall.
