b) Was talking
Explicação:
The Past Continuous Tense refers to a continuing action or state that was happening at some point in the past.
The Past Continuous Tense is formed by combining the past tense of "to be" (was/were), with the verbs present participle (-ing word).
In this case, the past tense of "to be", is single (was), because it is followed by "I".
The verb used is talk, and as explained, all you do is add "ing", so it would be talking.
So that is why the answer is: was talking.
