If in a LPP , the solution of a variable can be made infinity large without violating the constraints, the solution is _____________.

✅ The correct answer is option B.
If in a LPP , the solution of a variable can be made infinity large without violating the constraints, the solution is unbounded. An unbounded solution of a linear programming problem is a situation where objective function is infinite. A linear programming problem is said to have unbounded solution if its solution can be made infinitely large without violating any of its constraints in the problem.
