Which of the following is true in the context of marketing?

The correct answer is option 4- Labeling involves putting identification marks on the package.

Option 1: Advertising is a function of marketing, but it's not concerned with the cost and location of the target market. Market research and analysis handle those aspects. So, this statement is incorrect.

Option 2: Advertising is a one-way communication method, so there's no personal interaction or communication with the audience. This statement is incorrect.

Option 3: This statement is incorrect. Personal selling involves direct interaction and relationship building with potential customers, making it a two-way communication process.

Option 4: This is the accurate statement. Labeling involves putting identification marks, like brand names, logos, product information, and ingredients, on the packaging for product identification, description, and regulatory compliance.
