Answer:

(A)-electron

Step-by-step explanation:

Particles can be classified into:

- Leptons: particles which do not feel the strong interaction

- Hadrons: particles which interact by strong nuclear forces (they are actually not fundamental particles, since they are composed of quarks)

- Boson: the mediators of the four fundamental forces

The given options in this problem are:

(A)-electron --> LEPTON (because it does not feel the strong interaction)

(B)-proton --> HADRON (it consists of quarks)

(C)-neutron --> HADRON (it consists of quarks)

(D)-photon --> BOSON (it is the mediator of the electromagnetic force)

(E)-boson --> BOSON

So, the only lepton among the choices is (A) electron.
