A bead of mass `m` is located on a parabolic wire with its axis vertical and vertex at the origin as shown in figure and whose equation is `x^(2)=4ay`. The wire frame is vertical plane and the bead can slide on it without frictino. The bead is released from the point `y=4a` on the wire frace from rest. The tangential acceleration of the bead when it reaches the position given by `y=a` is `:`

A

`(g)/(2)`

B

`sqrt(3)(g)/(2)`

C

`(g)/(sqrt(2))`

D

`(g)/(sqrt(5))`
