Answer:

C.same as [H+]

Explanation:

Autoionization of water is expressed as H+ * OH-  = Kc

The value of Kc is 1*10^-14. Now simply plug thus in and the value of given H+ to solve

(1*10^-7) * OH- = 1*10^-14

OH- = 1*10^-7

Thus, in this scenario, the H+ and OH- ions have same concentration and solution is said to be neutral.
