Options

B. (6, 36, 90)
C. (8, 64, 160)
D. (12, 144, 360)

Answer

A

Explanation

Except the number group (4,16,48) , in all other number groups, the second number is the perfect, square of the first number while the third number is two and half times of the second number . (6,36,90)
`rArr 6 xx 6 = 36 and 36 xx 2 . 5 = 90`
(8, 64, 160)
`rArr 8 xx 8 = 64 and 64 xx 2 . 5 = 160`
12, 144, 360
But,
(4,16,48)
`rArr 4 xx 4 = 16 and 16 xx 3 = 48`
