    The equivalent circuit of a transformer has leakage reactance?s                                                                   \[{{X}_{1}},\,\,X{{'}_{2}}\] and magnetizing reactance                                                                              \[{{X}_{M}}\] , Their magnitudes satisfy

    A)                                                          \[{{X}_{1}}>>X{{'}_{2}}>>{{X}_{M}}\]            

    B)                                                           \[{{X}_{1}}=X{{'}_{2}}<<{{X}_{M}}\]

    C)                                                     \[{{X}_{1}}\approx X{{'}_{2}}>>{{X}_{M}}\]            

    D)                                                       \[{{X}_{1}}\approx X{{'}_{2}}<<{{X}_{M}}\]
