Pentane, $\text{C}_5\text{H}_{12}$, is reacted with chlorine under ultraviolet light. One of the products is compound $R$. $R$ has molecular formula $\text{C}_5\text{H}_{10}\text{Cl}_2$. Every molecule of $R$ contains one chiral carbon atom. In this isomer, which two atoms of the pentane chain could each be attached to chlorine atoms?
- A$1$ and $3$
- B$1$ and $5$
- C$2$ and $3$
- D$2$ and $4$
