A group of medical students carried out a detailed study on the impact of various factors on the different hormones during the menstrual cycle in a human female. They collected the data with different factors. Given below is the graph plotted from the data collected showing the morning temperature and concentration of hormones FSH, LH, estrogen and progesterone during normal menstrual cycle in a woman.
As per the data plotted in the graph, in which period of the menstrual cycle is the chance of the fertilisation very high in human female?
1. \(3^{rd}-9^{th}\) days
2. \(10^{th}-17^{th}\) days
3. \(18^{th}-23^{th}\) days
4. \(23^{rd}-28^{th}\) days
