a. Y>0, 3Y>0 -->-2X>3Y>0 --> X must be negative, suff
b. 2X+5Y<2Y-->20<2Y, Y>10, the same as A, so b suff

D should be best

Again
x=20; Y=-10
2.20+2.(-10)=20 2.-20+5.12

Also Again
X=-20; Y= (12)
2.-20+5.12=20


is it right or any other option left;

-2x > 3y => 2x + 3y < 0

1st stat
--------

y > 0 , than given eq can only true when x is -ve

2nd stat
-------

2x + 5y -20 = 0 => 2x + 3y = 20 - 2y , replacing it in given eq.

20 -2y < 0 => y > 10, so again x should be -ve to prove given eq true
