To convert energy from joules to electron volts (eV), we use the conversion factor:$\\ 1$ eV$= 1.6 \times 10^{-19}$ J$\\$Given:$\\$Energy required to break one bond in DNA$= 10^{-20}$ J$\\$We need to convert this energy into eV.$\\$Using the conversion factor:$\\ E_{eV} = \frac{E_{J}}{1.6 \times 10^{-19}} \\$Substitute the given energy:$\\ E_{eV} = \frac{10^{-20}}{1.6 \times 10^{-19}} \\$Simplify the expression:$\\ E_{eV} = \frac{10^{-20}}{1.6 \times 10^{-19}} = \frac{1}{1.6} \times 10^{-1} \\ E_{eV} = 0.625 \times 10^{-1} \\ E_{eV} = 0.0625 \\$The energy in eV is approximately $0.06. \\$Therefore, the correct option is Option 2.
