The correct answer is: B. Has, beaten
The verb “to beat” can be used in a number of different ways, but in this context it is being used in the sense of “to defeat” or “to overcome.” The past participle of “to beat” is “beaten,” so the correct answer is “has beaten.”
The other options are incorrect because they do not make sense in the context of the question. “Do” is the present tense form of “to do,” so it would not be used to talk about something that happened in the past. “Is” is the present tense form of “to be,” and “beaten” is not the past participle of “to be.” “When” is a question word, and it would not be used to make a statement about something that happened in the past.
Here is a more detailed explanation of each option:
- A. Do, beats
This option is incorrect because it uses the present tense form of “to do” and the present tense form of “to beat.” The question is about something that happened in the past, so the correct verb tense should be the past tense.
- B. Has, beaten
This option is correct because it uses the past tense form of “to have” and the past participle of “to beat.” The past participle of “to beat” is “beaten,” so the correct answer is “has beaten.”
- C. Is, beaten
This option is incorrect because it uses the present tense form of “to be” and the past participle of “to beat.” The past participle of “to beat” is “beaten,” so the correct answer is not “is beaten.”
- D. When, beats
This option is incorrect because it uses the question word “when” and the present tense form of “to beat.” The question is about something that happened in the past, so the correct verb tense should be the past tense.
