The statement “the limit of a constant times a function is the constant times the limit” follows from a combination of two fundamental limit principles. What are they?

(a)       The limit of a product is the product of the limits, and a constant is continuous.

(b)       The limit of a constant is the constant, and the limit of a product is the product of the limits.

(c)       The limit of a function is a constant times a limit, and the limit of a constant is the constant.

(d)      The limit of a product is the product of the limits, and the limit of a quotient is the quotient of the limits.

(e)       none of the above.
