Question : 42 of 160

Marks: +1, -0

If A - (-1 , 2) and B = (1 , -2) are two points and Pis a variable point such that the area of Δ PAB is always one. then the equation of the locus of P is

4x2 + 4xy + y2 = 1
x2 + 10xy + 25y2 - 34x - 170y = 0
x2 - 6xy + 9y2 + 22x - 66y - 23 = 0
16x2 - 24xy + 9y2 - 62xx + 34y + 46 = 0
