Answer:
The correct option is;
D. Neither is a function of the other
Step-by-step explanation:
The given parameters are;
The number of reps Tobias does in a day = A
The day in which Tobias does the reps = B
Therefore, given that the days are counting when and when he does not do reps, then B is independent of A, or B is not a function of A
Similarly, given that Tobias does reps every day, and the number of days are infinite, therefore, the number of reps, A is not a function of B, which gives;
Neither is a function of the other.
