Dear Abhingya x=at2 ...............1 y=bt....................2 put vallue of t from equation 2 to equation 1 x=a(y/b)2 y2=b2x/a so option a is correct Please feel free to post as many doubts on our discussion forum as you can.

Dear Abhingya
x=at2 ...............1
y=bt....................2
put vallue of t from equation 2 to equation 1
x=a(y/b)2
y2=b2x/a
so option a is correct
