has received
has been received
had received
had been received
Answer is Right!
Answer is Wrong!
The correct answer is: has been received.
The sentence is in the present perfect continuous tense, which is used to talk about actions that started in the past and are still happening now. In this case, the action is “receiving a written confirmation.” The sentence is also passive, which means that the focus is on the action itself, not on who is doing the action.
The other options are incorrect because they are not in the present perfect continuous tense. Option A, “has received,” is in the simple present tense. Option B, “had received,” is in the past perfect tense. Option C, “had been received,” is in the past perfect continuous tense.
Here is a more detailed explanation of each option:
- has received is in the simple present tense. This tense is used to talk about actions that happen regularly or repeatedly. In this case, the action is “receiving a written confirmation.” However, the sentence does not say that the person receives a written confirmation regularly or repeatedly. It only says that they have received one so far. Therefore, the simple present tense is not the correct tense to use.
- had received is in the past perfect tense. This tense is used to talk about actions that happened before another action in the past. In this case, the action is “receiving a written confirmation.” However, the sentence does not say that the person received a written confirmation before another action in the past. It only says that they have received one so far. Therefore, the past perfect tense is not the correct tense to use.
- had been received is in the past perfect continuous tense. This tense is used to talk about actions that started in the past and were still happening at a specific point in the past. In this case, the action is “receiving a written confirmation.” The sentence does say that the person received a written confirmation at a specific point in the past (so far). Therefore, the past perfect continuous tense is the correct tense to use.
