I believe the correct answer from the choices listed above is option A. Approximately, there will be 2.61x10^9 cans that will be recycled in 16 days. We calculate as follows:
113204 cans / min (60 min / 1 hr) (24 hr / 1 day) = 163013760 cans / day
163013760 cans / day (16 days) = 2.61x10^9 cans
Hope this answers the question.
