B) 4.6
C) 4.7
D) 7.4
E) 13.8
Alkaline
Having a pH greater than 7, indicating a base where concentration of hydroxide ions is greater than that of hydrogen ions.
Blood
A body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away.
pH

Final Answer :
D
Explanation :
The expected pH for blood is slightly alkaline, meaning it should be above 7.0. Option A, B, and C are all acidic and therefore unlikely to be the correct answer. Option E is extremely basic, which is also unlikely to be the correct answer. The only remaining option is D, which has a pH of 7.4, making it the best choice.
