To solve the problem, we can use the formula:

M1V1 = M2V2

Where:
M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume

Substituting the values, we get:

(9.0 M) V1 = (3.5 M) (0.25 L)

V1 = (3.5 M) (0.25 L) / (9.0 M)

V1 = 0.097 L = 97 mL

Therefore, we need 97 mL of the 9.0 M solution to make 0.25 L of a 3.5 M solution. The answer is C.
