Answer:
A. Trying to improve the product's performance
Step-by-step explanation:
A product at the maturity stage is well known to customers. It has its market share, but sales seem to grow at a sluggish pace. To keep the products' market vibrant, manufacturers tend to make positive variations on the product. Some of the variations include redesigning the package, adding new flavor, or improving its performance.
Improving the product's performance is a good way to maintain sales and increase the growth rate. Existing customers will have a reason to continue buying the product. The improved features attract new customers also.
