As we learnt in 

S - P Hybridisation -

When one S - and one P - orbital belonging to the same main shell of an atom are mixed together to form two new SP - orbitals.

- wherein

shapes

           Diagonal or Linear

 

In  \overset {1}C{H_{3}}-\overset {2}{C}\equiv \overset {3}{C}-\overset {4}C{H_{3}}  , carbon atoms 2 and 3  are SP hybridization and as we know SP orbitals form linear loads

 \therefore CH_{3}-C\equiv C-CH_{3} is a linear molecular.


Option 1)

CH_{3}-CH=CH-CH_{3}

Incorrect

Option 2)

CH_{3}-C\equiv C-CH_{3}

Correct

Option 3)

CH_{2}=CH-CH_{2}-C \equiv CH

Incorrect

Option 4)

CH_{3}-CH_{2}-CH_{2}-CH_{3}

Incorrect
