It is a well-known fact that during a total solar eclipse,the disk of the Moon almost completely covers the disk of the Sun. From this fact and the information given below,determine the approximate diameter of the Moon.
Distance of the Moon from the Earth $= 3.84 \times 10^{8} \; m$
Distance of the Sun from the Earth $= 1.496 \times 10^{11} \; m$
Diameter of the Sun $= 1.39 \times 10^{9} \; m$

• A
  $3.57 \times 10^{6} \; m$
• B
  $7.14 \times 10^{4} \; m$
• C
  $1.24 \times 10^{8} \; m$
• D
  $5.38 \times 10^{3} \; m$
