Explanation:

Step1: Identify relevant column/row

We need the value at the intersection of "Age 15 and above" row and "Car" column, or calculate it using column total.

Step2: Calculate missing value

The total number of students taking a car is 98. Students under 15 taking a car are 18. So:
$98 - 18 = 80$

Answer:

C. 80
