The past
continuous tense is used to show that an ongoing past action was happening at a
specific moment of interruption, or that two ongoing actions were happening at
the same time. It is formed using was/were + present participle (ing). The context refers to an
action yesterday which coincided with another action that was taking place.
This action can be indicated by “I was seeing off”, thus option C is correct.
“I’ve been seeing off” in option A indicates an action that started in the past
and may or may not be completed. It is present perfect continuous tense and in
incorrect in this context.
“I’ve seen off” in option B indicates a past action not defined by time of occurrence.
This is present continuous tense and it does not concur with the given context.
“I would see off” in option D is incorrect as it expresses the conditional mood indicating the
consequence of an imagined event or situation.
Thus, option
C is correct.
