A)
$\lambda=\large\frac{h}{mu}$
$\quad=\large\frac{6.626\times 10^{-27}}{200\times 5}$
$\quad=6.626\times 10^{-30}m/h$
Hence (c) is the correct answer.
Sir please don't mind..... Something is wrong......m=1/5 and v=5/3600 and h=6.626*10'-34 then answered is- 2.3760*10'-30. So answer is c correct. Your unit and mathode is wrong.
