Answer:
Correct Answer: D
Solution:
Addition - $ CH\equiv CH+2H_2\xrightarrow{Ni}CH_3-CH_3 $
Substitution - $ CH\equiv CH+Na\xrightarrow{{}}CH\equiv {C^{-}}N{a^{+}}+\frac{1}{2}H_2 $
Polymerization - $ 3CH\equiv CH\underset{Polymerization}{\mathop{\xrightarrow{hot}}} \underset{Polymer}{\mathop{C_{12}H_{18}}} $
