Let a point \(A\) be the intersection point of the sphere \(x^2 + y^2 + z^2 - 4x - 2y + 4z - 5 = 0\) and \(z\)-axis. Find the equations of all the tangent planes to the given sphere at the point \(A\).
\(2x + y + 3z + 15 = 0\), \(2x + y - 3z + 3 = 0\)
\(2x + y - 3z -15 = 0\), \(2x + y + 3z - 3 = 0\)
\(2x + y + 3z + 15 = 0\), \(2x + y + 3z - 3 = 0\)
\(2x + y - 3z - 15 = 0\), \(2x + y - 3z + 3 = 0\)
