Final answer:
Concentration, growth, integration, diversification, and investment reduction are correctly identified as various corporate level strategies employed to enhance company value and ensure long-term viability.
Step-by-step explanation:
Concentration, growth, integration, diversification, and investment reduction are indeed examples of different corporate level strategies. Concentration refers to a strategy that focuses on strengthening a company's position in its current business areas. Growth can be pursued organically through expanding operations or inorganically through mergers and acquisitions. Integration can be either backward, by taking control of supply chains, or forward, by taking over distribution paths. Diversification involves expanding into new markets or products, while investment reduction strategies might be employed to divest from non-core assets or reduce expenditures in certain areas. All these strategies are undertaken with the aim of enhancing the corporate value and ensuring the long-term sustainability of the business.
