Please can you help me with the question below.

The bottom answer would be (90°, -1)

The interval from highest to lowest score is 51 to 67, a range of 16 in the grade scores. The median is a score of 60 and would suggest that this is also roughly the average score. The IQR is 57-64, so 50% of the grade scores are between these limits. Q1=57, Q2=60, Q3=64. The whiskers show that the other 50% are divided unequally between the range 51-57 and 64-67, with more students being in the lower whisker than in the upper whisker.
