Answer:

To understand why the correct answer is option 'B', let's analyze the given sentence:

"This is the place that _______"

The sentence is incomplete and requires a verb to complete it. The verb should be in the past tense or present perfect tense because the sentence is referring to a past action or a completed action.

The options provided are:

a) I talked
b) I have been talking about
c) I have talking about
d) I was talked

Explanation of each option:

a) I talked - This option is in the simple past tense. However, the sentence requires a verb in the present perfect tense or past perfect tense to indicate a completed action or a past action that has relevance to the present.

b) I have been talking about - This option is in the present perfect continuous tense. It is the correct answer because it indicates an ongoing action that started in the past and is still happening or has just been completed. The use of the present perfect continuous tense is appropriate in this context because the speaker is referring to an action that has been happening over a period of time.

c) I have talking about - This option is incorrect because it does not have the correct verb form. The verb "talking" should be in the past participle form to match the present perfect tense. It should be "I have been talking about" instead.

d) I was talked - This option is in the past tense, but it is not appropriate in this context. The sentence requires a verb in the present perfect tense or past perfect tense to indicate a completed action or a past action that has relevance to the present.

Conclusion:

Based on the analysis above, option 'B' - "I have been talking about" is the correct answer. It is in the present perfect continuous tense, indicating an ongoing action that started in the past and is still happening or has just been completed.
