Explanation:

Step1: Identify reactants and products

Reactants: $\ce{CH4(g)}$, $\ce{Cl2(g)}$; Products: $\ce{CCl4(l)}$, $\ce{HCl}$ (assuming the incomplete product is $\ce{HCl}$ as it's a chlorination reaction).

Step2: Balance Carbon

Carbon atoms: 1 in $\ce{CH4}$ and 1 in $\ce{CCl4}$, so C is balanced.

Step3: Balance Hydrogen

Hydrogen atoms: 4 in $\ce{CH4}$, so we need 4 $\ce{HCl}$ (since each $\ce{HCl}$ has 1 H).

Step4: Balance Chlorine

Chlorine in $\ce{HCl}$: 4, and in $\ce{CCl4}$: 4, total Cl: 8. Each $\ce{Cl2}$ has 2 Cl, so number of $\ce{Cl2}$ needed: $\frac{8}{2} = 4$.

So the balanced equation is $\ce{CH4(g) + 4Cl2(g) -> CCl4(l) + 4HCl}$.

Answer:

A. $\ce{CH4(g) + 4Cl2(g) -> CCl4(l) + 4HCl}$ (assuming the full product for option A is as derived)
