    C

    Step-by-step explanation:

    The excluded values are the values of x that make the denominator of the rational function equal to zero as this would make the function undefined.

    Equate the denominator to zero and solve for x to obtain the values that x cannot be.

    x² - 2x - 35 = 0

    (x - 7) (x + 5) = 0 ← in factored form

    Equate each factor to zero and solve for x

    x - 7 = 0 ⇒ x = 7

    x + 5 = 0 ⇒ x = - 5

    Excluded values of x are x = - 5, x = 7 → C
