Quantization of Electric Charge

Steps:

• Recall the elementary charge $e = 1.6 \times 10^{-19}$ C, the fundamental unit carried by electrons or protons.
• Charge carriers transport integer multiples of $e$, so valid charges are $ne$ where $n$ is an integer.
• Divide each option by $e$ to check for integer $n$.
• Option C yields $n = 3$, an integer, confirming it as a possible charge.

Why C is correct:

• It equals $3e$ (since $3 \times 1.6 \times 10^{-19} = 4.8 \times 10^{-19}$ C), matching the law that charge is quantized in multiples of the elementary charge.

Why the others are wrong:

• A: $1.1 \times 10^{-19} / 1.6 \times 10^{-19} \approx 0.6875$, not an integer multiple.
• B: Identical to C, but the question specifies C as correct (possible formatting error).
• D: $$, not an integer multiple.

Final answer: C
