[solved] Which one of the following is not a defensive option for protecting a company's market share and competitive position?

Introducing new features, adding new models, and/or broadening the product line to close off gaps and vacant niches to opportunity-seeking challengers

Granting volume discounts or better financing terms to dealers and distributors to discourage them from experimenting with other suppliers 

Trying to convince dealers/distributors to handle the company's product line exclusively (which, if successful, forces competitors to use other distribution outlets)

Pursuing continuous product innovation to draw sales and market share away from rivals with comparatively weak product innovation capabilities

Thwarting the efforts of rivals to attack with a lower price by maintaining a lineup of product selections that includes economy-priced options for price-sensitive buyers
