Answer:

Step-by-step explanation:

The objective function of a linear programming problem is a linear function.
A valid objective function is (b) Min 4x+3y+(2/3)z
The form of the objective function of a linear programming problem is:

The above function means that:
- The objective function cannot contain the product of the variables
- The objective function cannot contain the quotient of the variables
The above highlights mean that:
- The objective function can contain the sum of the variables
- The objective function can contain the difference of the variables
Hence, the valid objective function is (b) Min 4x+3y+(2/3)z
