so would it be 4. A and B

I'm sorry. I goofed.

I didn't read carefully.

Your first answer -- A -- is correct.

To determine the correct answer, we need to calculate the time of the next low tide based on the given information.

We know that it takes 6 1/4 hours for the tide to change from high to low. Since the observation of high tide was made at 3:00 a.m., we can add 6 1/4 hours to find the time of the next low tide.

To simplify the calculation, we can convert the 1/4 of an hour into minutes. We know that 1 hour is equal to 60 minutes, so 1/4 of an hour is 15 minutes.

Adding the 6 hours to 3:00 a.m., we get 9:00 a.m. Then, adding the extra 15 minutes, we get 9:15 a.m.

Therefore, statement A that states "The next low tide will be at 9:15 a.m." is correct.

As a result, the correct answer is 1) A only.
