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
Thanks!

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).

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.
