The pattern does fit the exponential model of population growth, so statement I is true. However, the population also experienced an overshoot (when it exceeded the carrying capacity of the island) followed by a die-off (a sharp decrease in population), so statements II and III are also true. Therefore, the correct answer is D - II and III only.
