Answer:
B. Fact
Step-by-step explanation:
The highlighted text is a "fact" because it is expressing a statement that is real and is backed by evidence. For example, it states that "water is a basic human right." This is, indeed, an "objective reality." It also states that only 15% of the residents in the poor villages of Africa have access to drinking water. This is backed by evidence that the nearest drinking water is within a mile.
The statement is not a rhetorical question because it is not asking anything. It is also not a band wagon appeal because it doesn't persuade the reader to do anything or to think about something. It is simply stating a "fact."
So, this explains the answer.
