Answer 2

Answer:

Karin and his sisters will have been shopping at the mall before you come.

The correct option to be filled in the blank is (i) will have been shopping

Explanation:

• The subject-verb agreement in English grammar sometimes seems to be ambiguous.

• Thus it is important to figure out which one is the subject, and whether it is a singular number or plural, and then only we can decide on the verb.

• The action word tense gives us data around three unique regions.

• In the first place, the strained of an action word generally provides perusers with a feeling of time.
• At the end of the day, the action-word(verb) tense makes sense by assuming the activity in the sentence occurred beforehand (past tense), is occurring at present (current state), or will happen eventually (future tense).

• Second, tense can demonstrate ceaseless or repeating activity (moderate), an activity that has occurred starting around a specific time (great), an activity that started previously yet proceeds or repeats through right now (wonderful moderate).  
• And finally, regarding tenses we write and say, to make our meaning clear, we need to choose the correct tense for the timing and it needs to be sure to include all the needed words for that tense.
• Since the given statement relates the present to the future (Future dependency), the correct verb in the blank would be (i) will have been shopping

Hence the most appropriate answer is i) will have been shopping.
