The answer is O.
Since blood type A and B are codominant, it means that the people who have blood type AB only have genes of A and B. They do not have the gene for blood type O.
We can be sure that the child will not have blood type O by constructing a Punnett square. We can list all the possible genotypes thus predict their phenotypes. The capital letters represent the genotypes of parents, while others are the positive genotypes of offsprings.
From this, we can see that the only possible blood types their child could have are A, B, or AB. So, O is not possible.

You can use the pH scale
Explanation:
The pH scale ranges from 0-14 and is used to measure how acidic or basic a substance is!
Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system.
