Answer:
The correct answer is (A) Penetration pricing.
Explanation:
In this type of pricing, a product is initially priced low to quickly reach a large part of the market and to encourage the word of mouth marketing from consumers. This strategy works with the expectation that customers will be attracted to the new brand due to the low price. But in the case of batteries, the customer compares quality with a high price (Auger et al., 2010). So, this will not be considered as a successful pricing approach from Energizer.
