Consider a Population with the Following Numbers of Individuals Over $\tau$

Consider a population with the following numbers of individuals over time. year 1: 100
Year 2: 150
Year 3: 200
Year 4: 250
If the population size in year 5 is determined by a logistic model with delayed density dependence, r = 1.1, and K = 200 individuals, what value of $\tau$ would cause the population to decrease from year 4 to year 5?

A) $\tau$ = 0
B) $\tau$ = 1
C) $\tau$ = 2
D) $\tau$ = 3
