The correct answer is option B
The S-shaped graph (sigmoid) graph shows logistic growth. This is a pattern of growth in which the density of organisms increases slowly at first and then it increases fastly approaching an exponential growth.
Then it declines in a negative direction which shows the resistance of environment.
All these make a combinely make a graph called S-shaped graph. Mathematically all these ups and down makes it a logistic growth pattern graph.
