The growth of bacteria (lactobacillus) in milk leads to curd formation. A minimum bacterial population density of 0.8(in suitable units) is needed to form curd. In the graph below, the population density of lactobacillus in 1 litre of milk is plotted as a function of time, at two different temperatures, and  .
 
Consider the following statements based on the data shown above:
(i) The growth in bacterial population stops earlier at 37 °C as compared to 25 °C
(ii) The time taken for curd formation at 25 °C is twice the time taken at 37 °C
Which one of the following options is correct?
