The correct answer is: B. are having
The sentence is in the present continuous tense, which is used to talk about actions that are happening right now or that happen regularly. In this case, Ben and Ann are having breakfast at 8:30 AM.
The other options are incorrect because they are not in the present continuous tense. Option A, “have,” is in the simple present tense, which is used to talk about general facts or habits. Option C, “is having,” is in the simple present tense, which is used to talk about a single action that is happening at a specific time. Option D, “was having,” is in the past continuous tense, which is used to talk about actions that were happening at a specific time in the past.
Here are some examples of how the present continuous tense is used:
- I am eating a sandwich.
- We are going to the store.
- The baby is sleeping.
- The sun is shining.
