Fill in the blank with the most appropriate word. Don’t worry, I’ll do the shopping for you today; I ____ the office early on Fridays.

The correct answer is: C. leave

The sentence is about a person who is leaving the office early on Fridays. The most appropriate word to fill in the blank is “leave” because it is the simplest and most direct way to say that the person is going to be leaving. The other options, “will leave” and “will be leaving,” are both grammatically correct, but they are more formal and less natural-sounding. The option “am leaving” is not grammatically correct because it is a present tense verb form, but the sentence is about a future event.

Here is a more detailed explanation of each option:

• A. will leave is the simple future tense form of the verb “leave.” It is grammatically correct, but it is a bit formal and not as natural-sounding as the other options.
• B. will be leaving is the progressive future tense form of the verb “leave.” It is also grammatically correct, but it is even more formal than “will leave” and sounds even less natural.
• C. leave is the simple present tense form of the verb “leave.” It is the most direct and natural-sounding way to say that the person is going to be leaving.
• D. am leaving is the present progressive tense form of the verb “leave.” It is not grammatically correct because it is a present tense verb form, but the sentence is about a future event.
