Two straight lines rotate about two fixed points (-a, 0) and (a, 0) in antic clockwise direction. If they start from their position of coincidence such that one rotates at a rate double of the other, then locus of curve is

A

`x^2 + y^2 + ax -3a^2=0`

B

`x^2 - y^2-2ax -3a^2 = 0`

C

`x^2+y^2 -2ax-3a^2 = 0`

D

`x^2 - y^2 + 2ax -3a^2=0`
