de-broglie wavelength = h/mv

 

here h is placks constant and v is same speed considered for all.

It means particle which has larger mass will have les wavelength.

Now U can calculate!

 

 

Plz approve!

 de-broglie wavelength =  h/mv

as speeds are same and h is planck''s constant so

   finally wavelength is only inversely proportional to their masses..

and as electon has smallest mass of all three so de broglie wavelength for elrctron is largest.

i.e opt (a)_ is correct..
