• A. A-E,B-H,C-G,D-I
• B. A-I,B-E,C-H,D-F
• C. A-H,B-F,C-I,D-E
• D. A-F,B-G,C-E,D-H

Answer 1

The correct option is B A-I,B-E,C-H,D-F

GRAVITATION -the theoretical quantum of gravitation, usually assumed to be an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of two. like photon.

BARYONS-a subatomic particle, such as a nucleon or hyperon, that has a mass equal to or greater than that of a proton.

PIONS--Pions a pion is any of three subatomic particles: π0 , π+ , and π− . Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons

LEPTONS-A positron is a lepton, because it is an anti-electron. An electron is a lepton, and a particle falls under the same classification as its antiparticle. This can also be shown to be true because a lepton is defined as a particle that does not experience the strong nuclear force, and positrons, like electrons, do not.
