The correct answer is D. I’ll get.
The sentence is about the speaker’s intention to take a taxi. The speaker is tired and does not want to walk home. The speaker is planning to take a taxi in the near future. The verb “get” is the most appropriate verb to use in this sentence because it expresses the speaker’s intention to take a taxi.
The other options are not as appropriate. Option A, “I have got,” is in the past tense. It does not express the speaker’s intention to take a taxi in the near future. Option B, “I am getting,” is in the present progressive tense. It expresses the speaker’s action of getting a taxi. However, the speaker is not currently getting a taxi. The speaker is planning to get a taxi in the near future. Option C, “I got,” is in the simple past tense. It expresses the speaker’s action of getting a taxi in the past. However, the speaker is not talking about getting a taxi in the past. The speaker is talking about getting a taxi in the near future.
