The Correct Option is D

Solution and Explanation


The number of normals to a parabola \(y^2 = 4ax\) that can be drawn through a given point \((x_1, y_1)\) is given by solving the equation of the normal to the parabola. In this case, solving for the number of normals through the point \( (9,6) \) gives us 3 solutions. Thus, the correct answer is \(\boxed{3}\).
