From question we can say D/8=|y-x|
Statement 1 : D/8= |1.5-X| .... Not sufficient
Statement 2 : D/8= 1.2....we can derive D......Hence X can be determined and statement 2 is sufficient........Answer is B
Statement 1 : D/8= |1.5-X| .... Not sufficient
Statement 2 : D/8= 1.2....we can derive D......Hence X can be determined and statement 2 is sufficient........Answer is B

I got this wrong earlier and i may be wrong again lol
I see 8 "open boxes" equally spaced, but i also got to keep in mind this is a number line. Can be negative to zero to positive.
(1) Insufficient because we don't know x and the distance between each tick.
(2) 4/8 of the total boxes = distance between y and x ; 1/2 B = 1.2 ; B = 2.4 (total) ; 2.4/8 = 0.3
B

So Statement 2 is not sufficient.
