The correct answer is: B. starts
The word “start” is the most appropriate word to fill in the blank because it is the simple present tense form of the verb “to start.” The simple present tense is used to talk about things that happen regularly or repeatedly. In this case, the speaker is saying that their working day usually starts at 8:30 sharp.
The other options are not as appropriate because they do not express the idea of regularity or repetition. The word “would start” is in the past tense, which would be used to talk about things that happened in the past. The word “won’t start” is in the negative, which would be used to talk about things that are not going to happen.
Here are some examples of how the word “start” can be used in a sentence:
- My working day starts at 8:30 sharp.
- The race starts at 10:00 AM.
- The meeting starts in 5 minutes.
- The movie starts at 7:00 PM.
- The new school year starts in August.
