Hint- In order to solve the problem go through the rules of North-West Corner rule and then find the disadvantage accordingly.

Complete step-by-step solution:
The north-west corner rule is a method adopted to compute the initial feasible solution of the transportation problem. The name north-west corner is given to this method because the basic variable is selected from the entrance left corner.
 In the case of transportation problem the north-west corner rule does not take into account the cost of transportation
Hence, option B is the correct option.

Note- The north-west corner rule is easiest to solve transportation problems, students can come across the disadvantages of this rule only after solving some problem by this rule.
