According to the question what I feel is there must be options given. And from those options we had to select the correct answer to this question.
Since no option is given over here so the answer to this question will be infinite.
For example:- someone wants to buy 100 pens but it won't be possible from the above 3 combination of boxes. Similarly we cannot buy thousand pens as well and so on. Therefore the answer will be infinite until and unless any option is given.
