Answer:

B. The rate at which the balloon is rising.

Step-by-step explanation:

Mathematically speaking, the slope of the line represents the change in dependent variable (Height) divided by the change in independent variable (Time). According to the graph, a postive change in time leads to a positive change in height, meaning that slope is positive. Physically speaking, the slope represents the rate of change at which the height of the ballon is rising.

Hence, correct answer is B.
