Solution : The correct answer is (b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

The assertion is true. Marketing management does aim to create and maintain profitable customer relationships. It involves various activities like market research, product development, pricing strategies, distribution, advertising, promotion, and more, all with the goal of building and sustaining relationships with customers to drive profitability.

The reason is not the correct explanation. The reason incorrectly states that marketing management is exclusively focused on advertising and promotion. While advertising and promotion are important components of marketing management, they are not the exclusive focus. Marketing management involves a broader spectrum of activities beyond advertising and promotion to create and maintain customer relationships.

In summary, both the assertion and reason are true, but the reason does not correctly explain the assertion.
