What is the sequence of increasing melting point for the three chlorides shown? $\text{CCl}_4$, $\text{MgCl}_2$, $\text{PCl}_5$
- A$\text{CCl}_4 \rightarrow \text{PCl}_5 \rightarrow \text{MgCl}_2$
- B$\text{MgCl}_2 \rightarrow \text{CCl}_4 \rightarrow \text{PCl}_5$
- C$\text{MgCl}_2 \rightarrow \text{PCl}_5 \rightarrow \text{CCl}_4$
- D$\text{PCl}_5 \rightarrow \text{CCl}_4 \rightarrow \text{MgCl}_2$
