A constant is a number, or a letter that represents a number that
never changes. From the time the problem starts until as long
as it lasts, its value is constant.
A variable is a letter that stands for a number that can change.
A coefficient is each of the items in a group of them that are all
multiplied together.
Example: 17x + 4y
That's an expression with two terms.
The terms are '17x' and '4yz'.
In the first term:
'17' is the numerical coefficient.
'x' is the literal coefficient.
In the second term:
'4' is the numerical coefficient.
'y' and 'z' are both literal coefficients.

c. never
EXPLANATION
When we have
in mathematics, we call b the divisor.
In mathematics, division by zero is not defined.
We cannot divide a function, or a number by zero and get a value.
That is why, there is the restriction, b≠0
Therefore, zero is never a divisor.
The correct answer is C
