The Correct Option is B
Solution and Explanation
Concept:
North-West Corner Rule (NWCR) is used to obtain an initial basic feasible solution in transportation problems.
Step 1: Nature of NWCR.
• Provides feasible allocation
• Does not consider cost minimization
Step 2: Evaluate option A.
Optimal solution:
• Requires further optimization (MODI, etc.) Hence false.
Step 3: Evaluate option B.
NWCR gives:
• Initial feasible solution Hence true.
Step 4: Evaluate option C.
Solution is always feasible → false.
Step 5: Evaluate option D.
Vogel’s method is separate technique → false.
Step 6: Final conclusion.
\[ \boxed{\text{Answer: B only}} \]
