    In this problem, the answer would be B. A water and ammonia solution with a pH level of 11.

    If the human blood has an approximate pH level of 7.3, then the substance that is more basic than the human blood would be water and ammonia solution with a pH level of 11. Determining acids and bases is easier when their pH level is determined since this is the scale used for such. Those that have a pH level of below 7, they are considered acidic. Thus, a human stomach's digestive juices with a pH level of 2, apple juice with a pH level of 3, and grape juice with a pH level of 4.5 would all fall as acidic.
