I would have to agree that a 5% increase may not seem like much for the consumer (especially if the product price is low already). Also, a 5% increase in profits shows the consumers that the company is not trying to gouge the buyers.
The most likely company to have such an objective would be one that is relatively well established. A 5% increase in profits is not a huge increase and therefore would not seem very good for a new and rising company. So this would be more appropriate for a company like, for example, McDonalds.
Option e) would certainly apply to some sort of luxury item, like a high-end automobile or a designer watch. Most businesses have more of an interest in competitive pricing, but those companies attempting to establish a niche might try to raise their prices in the interest of pitching their product as luxury, or high quality.
