    Answer : Option D

    Explanation :

    ATQ, loga [1/36] = -2/3

    We know that loga y = x is similar to ax = y

    So, a (-2/3) = 1/36

    Or, a (-2/3) = 1/62

    Or, a (-2/3) = 6-2

    Now, multiply and divide by 3 in the power of 6 to make the power equals to power of a.

    So, a (-2/3) = 63(-2/3)

    On comparing both side, we get a = 63

    Therefore, a = 216
