Explanation:

The 4Ps marketing mix concept (also known as the 4ps of marketing) was introduced by Jerome McCarthy in his book: "Basic Marketing: A Managerial Approach".
The four Ps of marketing are the key factors that are involved in the marketing of a good or service. They are the product, price, place, and promotion of a good or service. Often referred to as the marketing mix, the four Ps are constrained by internal and external factors in the overall business environment, and they interact significantly with one another.

The 4 Ps are used by companies to identify some key factors for their business, including what consumers want from them, how their product or service meets or fails to meet those needs, how their product or service is perceived in the world, how they stand out from their competitors, and how they interact with their customers.
