When an organization comes to the realization that there are quality problems in products that are already in service, ethical approaches include: (I) divulging the information to the public at large. (II) recalling, if possible, affected products. (III) handling complaints on an individual rather than a systemic basis.

The answer is (I) and (II)

Explanation:

The ethical thing to do is first inform the public of the quality problems of the product, this is to prevent the public from making purchases they will later regret and this will lead to the company losing them as customers.

Also this quality problem may be something that will be injurious to people, and in order to avoid health challenges, it is best that companies inform the public.

Another thing that would be ethical for the company to do is recall the products with quality problems. This is also geared towards making sure that the risk of the public buying the affected products is reduced to the barest minimum.
