The right option is "The value of the variable makes the denominator zero".

Step-by-step explanation:

We have to find the option from the following situations that best describes why excluding the value of a variable from the denominator of an algebraic fraction is necessary.

The right option is "The value of the variable makes the denominator zero".

So, if the denominator of a function is zero, then the function becomes undefined and hence, we have to exclude that value of the variable which makes the denominator equals to zero. (Answer)
