    Option-B CH3-CH= CH-CH3

    Explanation:

    Isomers are defined as those compounds which have same molecular formula but structural formula. This means that isomers differ from each other only in connectivity patterns. Tho solve this problem we will find out the molecular formula of each given compound and then will compare to the reference compound.

    Reference Compound:

    CH2= CH- CH2-CH3

    Molecular Formula = C₄H₈

    Option-A:

    CH3-CH3= CH3-CH3

    Molecular Formula = C₄H₁₂

    Option-B:

    CH3-CH= CH-CH3

    Molecular Formula = C₄H₈

    Option-C:

    CH3-CH2-CH2-CH3

    Molecular Formula = C₄H₁₀

    Option-D:

    CH3-CH-CH2-CH3

    Molecular Formula = C₄H₉

    Result:

    As it can be seen that Option-B has the same molecular formula as the reference compound. Hence, it is the correct answer.
