Correct answer · Option 4
\( \text{CH}_4 \)
Explanation
Methane \( (\text{CH}_4) \) undergoes substitution with \( \text{Br}_2 \) to form \( \text{CH}_3\text{Br} \). Wurtz reaction on \( \text{CH}_3\text{Br} \) gives ethane \( (\text{CH}_3\text{CH}_3) \), which is a gaseous hydrocarbon with 2 carbons (less than 4).
