    A
    `250001`

    B
    `251001`

    C
    `260110`

    D
    `261001`

    Note: Use of formula, `( a^2 + b^2 + 2ab) = (a+b)^2` We have, `387 xx 387 + 114 xx 114 + 2 xx 387 xx 114` `=(387)^2 + (114)^2 + 2 xx 387 xx 114` `=(387 + 114)^2 =(501)^2 = (500 + 1)^2` `=(500)^2 + (1)^2 =2 xx 500 xx 1` `=250000 + 1 +1000 = 251001`
