The cause of the quantization of electric charge is the transfer of an integral number of electrons. Charge is always transferred in discrete units of the elementary charge (e), where e = 1.6 × 10⁻¹⁹ C. Since electrons are the fundamental charge carriers, charge cannot exist in fractional values of e.
Thus, the correct answer is (c) transfer of integral number of electrons.

    1. The quantization of electric charge occurs because charge is transferred in discrete units of the elementary charge e, which is the charge of an electron or proton. This means charge always exists in integral multiples of e, never in fractions.
      Answer: (c) transfer of integral number of electrons.
