A. \(4 \to 6 \to 3 \to 5 \to 2 \to 1.\)
B. \(2 \to 4 \to 3 \to 6 \to 5 \to 1.\)
C. \(3\to 4\to 2\to 6\to 5\to 1.\)
D. \(6\to 4\to 2\to 3\to 5\to 1.\)
B
\(\begin{array}{l}
2C{H_4} \to CH \equiv CH + 3{H_2}\\
CH \equiv CH + {H_2} \leftarrow C{H_2} = C{H_2}\\
C{H_2} = C{H_2} + {H_2}O \leftarrow C{H_3}C{H_2}OH\\
2C{H_3}C{H_2}OH \to C{H_2} = CH - CH = C{H_2} + {H_2} + 2{H_2}O\\
nC{H_2} = CH - CH = C{H_2} \to - {\left( {C{H_2} - CH = CH - C{H_2}} \right)_n} -
\end{array}\)
