Answer:
(A) In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers' health.
Explanation:
Option A is the right answer, this is because, option A tells us the reason why the sales of apples fell in the following month.
In other words, since majority of the consumers are indifferent to the report, then, considering the listed options, it can only be the unavailability of the apples that caused the sharp reduction in sales.
Hence, the correct answer is "In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers' health."
