First I think that Rutherford used Alpha particles in his gold foil experiment! Isnt it?
I am not sure but what I remember is this only!

DO THE BEST AND HOPE FOR THE BEST!!
RESULT IS NOT IN YOUR HANDS!!!
HAVE A NICE DAY!!!

the answer is wave properties of the electron because this is the only characteristic of the given four options which was undiscovered at that time.morever if a beam of electrons would have been projected that will become a case of absorption spectrum which is a wave like property of electron. plzzzzz rate me i'm correct. cheers

there are numerous options besides I.I.T

look at it logically, it cant be charge or mass, since the electron mass is negligible and it wud nt show any obvious effects, now since the foil is very very thin, we can only assume that th elestrons manage to slip throught he foil, and show up on a ZnS screen on the other end, thus we assume the electron to have no mass at all. which leads us to wave properties.
this was just a logical thought process.
i might be very very wrong /

Thank u both for ur views . Just one small doubt -
when electron beam is passing near the nucleus , it will suffer attraction . Is it possible that it collides with the nucleus ???

it will suffer attraction but at the same time it will also suffer repulsion from electrons in the atom, hence there will be no collision.
