    Answer: a. - 4°C.

    b. He is incorrect because temperature is a vector quantity.

    Step-by-step explanation:

    We know that the temperature is a vector quantity because it has both magnitude and direction.

    The value of T represents the temperature that is 4 degrees C below zero is written as - 4°C.

    Also, if a student says that "T represents only positive numbers and zero, because there is no negative sign," then he is incorrect because temperature is a vector quantity (it can be negative).
