Match List I with List II and select the correct answer using the codes given below the Lists: List I (Characteristic) - List II (Particle) 1. I. Zero mass - A) Positron 2. II. Fractional charge - B) Neutrino 3. III. Fractional spin - C) Quark 4. IV. Integral spin - D) Phonon Codes:

1. I. Zero mass (or near-zero rest mass) is characteristic of the Neutrino (B). 2. II. Fractional charge (e.g., +2/3e or -1/3e) is characteristic of Quarks (C). 3. III. Fractional spin (e.g., 1/2) is characteristic of fermions like the Positron (A), electron, proton, neutron, quark, neutrino. 4. IV. Integral spin (e.g., 0, 1) is characteristic of bosons like the Phonon (D) (quantum of lattice vibration, spin 1). 5. The correct matching is I-B, II-C, III-A, IV-D.
