Answer:
a. Column A should be “Time,” and Column B should be “Position.”
Step-by-step explanation:
Column A is on x-axis and x-axis always represent independent variable.
Column B is on y-axis and y-axis always represent dependent variable.
In all the given option only time and position are related to each other. Speed and velocity has same magnitude so it can not be plotted in a graph.
Thus, Column A should be “Time,” and Column B should be “Position.”
