Explanation

The correct answer is B (Lin-log model). The lin-log model is a functional form of simple linear regression where only the independent variable is in logarithmic form. This distinguishes it from:

• A (Log-lin model): Incorrect because in this model, the dependent variable is in logarithmic form, while the independent variable is not.

• C (Log-log model): Incorrect because this model involves both the dependent and independent variables being in logarithmic form. The question specifies that only the independent variable is logarithmic, making the lin-log model the appropriate choice.
