    C)                  DCM and \[{{H}_{2}}O\] would stay as lower and upper layer respectively in the S.F.

    D)                  DCM and \[{{H}_{2}}O\] will be miscible clearly

    Correct Answer: C

    Solution :

    DCM has higher density and it is immiscible with water it will form lower layer and water will form upper layer in separating funnel
