Step-by-step explanation:
P&G most likely uses the related constrained diversification strategy to create corporate relatedness.
The related constrained diversification strategy refers to a situation where a company expands its operations into new products or services that are related to its existing product line or business. In this case, Procter & Gamble's paper towel and baby diaper businesses are both related to its paper production plant, as they use paper products as inputs.
By using the related constrained diversification strategy, P&G is able to leverage its expertise and resources in the paper industry to create corporate relatedness. This means that the different businesses within the company can benefit from shared resources, knowledge, and capabilities, leading to operational efficiencies and competitive advantages.
