In case the given numbers are :
81 63 61 58 72 70 79 68 82 64 54 82 72 63 64 76 57 64 73 58
we have :
50-59 , frequency is 4 (58, 54, 57, 58)
60 - 69, frequency is 7 ( 63, 61, 68, 64, 63, 64, 64)
70 - 79, frequency is 6 (72, 70, 79, 72, 76, 73)
80-89, frequency is 3 (81, 82, 82)
So correct option which matches the above data is option second.
