The correct answer is:
1
Given parabola $x^{2}=4 a y$
It is passes through $(2,1)$
$\therefore \quad 4=4 a$
$\therefore$ Length of latus rectum of parabola $x^{2}=4 a y$ is $4 a$
$\therefore \quad 4 a=4$
$\therefore \quad a=1$
It is passes through $(2,1)$
$\therefore \quad 4=4 a$
$\therefore$ Length of latus rectum of parabola $x^{2}=4 a y$ is $4 a$
$\therefore \quad 4 a=4$
$\therefore \quad a=1$
