Explanation:

Milk of magnesia ($Mg(OH)_2$) is a base used to neutralize excess stomach acid. Bases have a pH greater than 7. A pH of 4 is acidic, a pH of 7 is neutral. A pH of 14 is a very strong base and milk of magnesia is not that strong. A pH of 10.5 is a reasonable value for a basic substance like milk of magnesia.

C. 10.5
