A proton has a mass of 1.67 × 10⁻²⁷ kg.

Which of the following shows the conversion of this mass to GeV/c²?

$\frac{1.67 \times 10^{- 27} \times 1.60 \times 10^{- 10}}{{(3.00 \times 10^{8})}^{2}}$
$\frac{1.67 \times 10^{- 27} \times 1.60 \times 10^{- 19}}{{(3.00 \times 10^{8})}^{2}}$
$\frac{1.67 \times 10^{- 27} \times {(3.00 \times 10^{8})}^{2}}{1.60 \times 10^{- 10}}$
$\frac{1.67 \times 10^{- 27}}{1.60 \times 10^{- 10} \times {(3.00 \times 10^{8})}^{2}}$
