• A. femto
• B. nano
• C. pico
• D. atto

Answer: (A)

Verified step by step guidance

1. Recall that metric prefixes represent powers of ten and are used to express very large or very small quantities in a more manageable form.
2. Identify the exponent in the given multiplier: \$1.0 \times 10^{-15}$, which means the quantity is scaled by ten to the power of negative fifteen.
3. Match this exponent to the standard metric prefixes: for example, nano corresponds to \$10^{-9}\(, pico to \)10^{-12}\(, femto to \)10^{-15}\(, and atto to \)10^{-18}$.
4. Since the multiplier is \$10^{-15}\(, the correct metric prefix is the one associated with \)10^{-15}$, which is femto.
5. Therefore, the metric prefix corresponding to \$1.0 \times 10^{-15}$ is femto.
