Answer:
Option D
Explanation:
Option A and B is not correct because a neutron is a negatively charged sub atomic particle while in the question it is given that X carry negative charge
On the other hand proton is a positively charged particle with a charge of +1
And it will be attracted towards a negatively charged particle only. Hence, option C is also in correct
X being negatively charged can be an electron which has a charge of -1. Since it is negatively charged, it is easily attracted towards a positively charged particle i.e proton.
Hence, option D is correct
