JEE Math Practice Question

Let the focal chord of the parabola $$\mathrm{P}: y^{2}=4 x$$ along the line $$\mathrm{L}: y=\mathrm{m} x+\mathrm{c}, \mathrm{m}>0$$ meet the parabola at the points M and N. Let the line L be a tangent to the hyperbola $$\mathrm{H}: x^{2}-y^{2}=4$$. If O is the vertex of P and F is the focus of H on the positive x-axis, then the area of the quadrilateral OMFN is :

1. A.$$2 \sqrt{6}$$
2. B.$$2 \sqrt{14}$$
3. C.$$4 \sqrt{6}$$
4. D.$$4 \sqrt{14}$$
