The period is 3.0 days, so go along the x axis to 3.0 and up to find the value on the y axis at 2.8

Oh God I was taking the fourth day as the third day and it took your comment to realise that the graph started from 1:facepalm:
Thanks!

I understand that you have gotten the answer. But be careful about the MS. I would not recommend that you read the y-axis value as 2.8 because the line clearly shows it does not cross at 2.8 but above 2.8.
Certain exam boards mark the structured question with some deviations from the MS but they reflected their marking in the examiner reports. MS is just a guidline(s).
