CASE-I
BY SOLVING QUAD EQ, WE GET X=-2 AND X=1. SO NO UNIQUE VALUE. HENCE AD CAN BE ELEMINATED
CASE-II, AGAIN SOLVING QUAD EQ, WE GET X=-3 AND X=1. AGAIN NOTSUFFICIENT SINCE NO UNIQUE VALUE IS THERE
BUT WHEN WE COMBINE BOTH CASES, WE GET COMMON X WHICH IS EQUAL TO 1.
SO MY ANSWERL WILL BE C
PLEASE CORRECT ME, IF I AM WRONG.
