Answer 1

Both are blue.

Step-by-step explanation:

Remember that litmus indicator solution turns red in acidic solutions and blue in alkaline (basic) solutions.

In this case, NaOH is a base (specifically, a strong base). So if we dip the red litmus, it will turn blue and the blue litmus would stay blue, so the answer is that both are blue.
