A tank initially contained a certain amount of water, and over the time interval from 0 to 11 hours, the amount of water in the tank changed. This change was modeled by a differentiable function n(t), where t represents time measured in 5 hours the function n(t) evaluates to 26 gallons, indicating that at that specific time, there were 26 gallons of water in the tank.
What is the best interpretation of the statement regarding the water tank scenario?
a) The rate of change of water in the tank is constant.
b) The tank initially contained 26 gallons of water.
c) The function n(t) is increasing over the interval 0 < t < 11.
d) There were 11 gallons of water in the tank at t = 0.
