    Answer:  The correct option is (C). (2, -5).

    Step-by-step explanation:  The given function is

    g(x)=3x^2-12x+7.

    The vertex form of the function g(x) is g(x)=3(x-2)^2-5~~~~~~~~~~~~~~~~~~~~~~(i)

    We know that if the vertex form of a function f(x) is written as

    f(x)=a(x-h)^2+k,

    then its vertex is (h, k).

    So, from equation (i), we can say that the vertex of function g(x) is

    (2, -5).

    Thus, (C) is the correct option.
