    The molecule has 2 double bonds

    Explanation:

    Corresponds to propanediene (alkene with 3 carbons and 3 double bonds).

    When saying the statement that it is a 3-carbon alkene, the only option is that it has two double bonds:

    H2C = C = CH2 (carbon has 4 valence, sharing 4 electrons)
