    Assertion: All the hydrogen atoms in \[C{{H}_{2}}=C=C{{H}_{2}}\] lie in one plane.
    Reason: All the carbon atoms in it are \[s{{p}^{2}}\] hybridized.

    A) If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
