Final answer:

The sum of 4H2O and -4 is a combination of a chemical quantity and a numerical value, which cannot be further simplified, resulting in 4H2O - 4.

Step-by-step explanation:

The question presented is asking for the sum of the chemical quantity 4H2O and the numerical quantity -4. When combining chemical quantities with numerical values, the result is not a straightforward numerical sum but rather a combination that includes both the chemical and numerical components.

Therefore, the sum of 4H2O and -4 is best represented as 4H2O - 4, which doesn't simplify further because they are not like terms. So the correct answer is option C: 4H2O - 4.
