(A) The structure is $CH_3-CH=CH-C\equiv CH$. Counting the bonds: $C-H$ bonds: $3$ (in $CH_3$) $+ 1$ (in $CH$) $+ 1$ (in $CH$) $+ 1$ (in $CH$) $= 6$ $\sigma$ bonds. $C-C$ bonds: $1$ $(C-C)$ $+ 1$ $(C=C)$ $+ 1$ $(C-C)$ $+ 1$ $(C\equiv C)$ $= 4$ $\sigma$ bonds. Total $\sigma$ bonds $= 6 + 4 = 10$. $\pi$ bonds: $1$ (in $C=C$) $+ 2$ (in $C\equiv C$) $= 3$ $\pi$ bonds. Therefore,the total is $10\sigma$ and $3\pi$ bonds.

Number of $\sigma$ and $\pi$ bonds present in $CH_3-CH=CH-C\equiv CH$ are
