(1) x < 8 and y < 3
(2) x^3 < 8 and y - 8 < 0


x & y are positive numbers and NOT necessarily integers

(1) x < 8 & y < 3 ... take numbers. x = 7.5 & y = 2.5 gives "No" and x = 1 & y = 1 gives "Yes" . Hence Insuff

(2) x^3 < 8 : x < 2 & y < 8

Hence x*y < 2*8 < 16 Suff

Hence Option (B) is our answer.

I) if x=7.5 and y=2.5 then xy>16
Whereas for values x=4 and y=2 xy<16
Insufficient

II) as per statements
x<2 and y<8
When x=2 and y=8 then xy=16
So xy<16
Sufficient

B is answer
