Given,

To define the objective of a Linear programming Problem.

As per the definition of the Linear Programming Problem,

A Linear programming problem is a linear function (also known an objective function) subjected to certain constraints for which we need to find an optimal solution ( i.e. either a maximum/minimum value) depending on the requirement of the problem.

From the above definition, we can clearly say that, Linear programming problem’s objective is to either maximize/ minimize a given objective function, which means to optimize a function to get an optimum solution.

Hence the answer is option B.
