Step-by-step explanation:
The answer is Option 2: Return on Investment (ROI). Return on Investment (ROI) is a financial metric that measures the profitability of an investment. It is used to determine how marketing activities contribute to the firm's financial success by calculating the return generated from the marketing investment.
For example, if a company invests $1000 in a marketing campaign and generates $2000 in revenue as a result, the ROI would be ($2000 - $1000) / $1000 = 1, or 100%. A positive ROI indicates that the marketing efforts have contributed to the firm's financial success.
