The lengths of the two focal chords of the parabola $y^2=16 x$ is 25 units each. If these two chords cut the parabola at A, B, C and D, then the area (in sq. units) of the quadrilateral formed by $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and D is

• A

  $\frac{625}{2}$
• B

  $180$
• C

  $150$
• Correct answer
  D

  $300$

Hence, the correct answer is option: 'D'.
