Answer: The correct option is
(D)
Step-by-step explanation: We are given that the greatest value of n is 9.
We are to select the inequality that best shows all the possible values of n.
Since the greatest value of n is 9, it means that the value of n is less than or equal to 9.
But the values of n cannot be greater than 9.
So, we will be using the sign of less than or equal to in the inequality.
Therefore, the required inequality that best shows all the possible values of n is given by
Thus, (D) is the correct option.
