<h2>
Answer:</h2>
Option: A is the correct answer.
A. Two students are the same age but have different heights.
<h2>
Step-by-step explanation:</h2>
The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .
This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.
Hence, option: A is the correct answer.
