In the above-given series, add squares of natural numbers to the previous numbers to obtain the next numbers.
58 + (2)
2
= 58 + 4 = 62
62 + (3)
2
= 62 + 9 = 71
71 + (4)
2
= 71 + 16 = 87
87 + (5)
2
= 87 + 25 = 112
112 + (6)
2
= 112 + 36 = 148
So, 148 is the missing number of the series. Hence, the second option is correct.
