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

Let's match the characteristics to the particles: I. Zero mass: Neutrinos (B) were historically thought to have zero mass, although now known to have a very small, non-zero mass. Among the options, Neutrino is the best fit for 'Zero mass' in a simplified context compared to others. II. Fractional charge: Quarks (C) are elementary particles that carry fractional electric charges (+2/3e or -1/3e). III. Fractional spin: Particles with half-integer spin (like 1/2, 3/2, etc.) are called fermions. Positrons (A), Neutrinos (B), and Quarks (C) are all fermions and have spin 1/2, which is fractional. Given the other matches, Positron is matched here. IV. Integral spin: Particles with integer spin (like 0, 1, 2, etc.) are called bosons. Phonons (D) are quasiparticles representing quantized modes of vibration occurring in a rigid crystal lattice and are bosons, thus having integral spin. Matching these gives: I-B, II-C, III-A, IV-D. This combination aligns with option A.
