A. It is an acid.
B. It is a base.
C. It is not an acid.
D. It is not a base.



Answer :

Final answer:

Yasmin can conclude the sample is not a base if the red litmus paper remains red.


Explanation:

If the red litmus paper remains red after being dipped into the solution, Yasmin can conclude that the sample is not a base. Red litmus paper stays red in the presence of acids and does not change color, indicating that the solution is not a base.
