Batch costing applies to identical items produced in discrete groups

Steps:

• Identify batch costing: accumulates costs for groups of identical units, common in repetitive manufacturing.
• Evaluate options: match each business to costing methods like job (unique/custom) vs. batch (standardized batches).
• Compare scale and customization: large, unique projects use job costing; smaller, repeatable parts use batch.
• Select best fit: car components involve producing identical parts in batches for assembly lines.

Why B is correct:

• Car component manufacturers produce standardized parts (e.g., bolts, gears) in batches, allowing costs to be tracked per batch under batch costing definition.

Why the others are wrong:

• A: Aircraft are custom-built, requiring job costing for unique projects.
• C: Ships are large, one-off constructions, suited to job costing.
• D: Wedding cakes are personalized, using job costing for individual orders.

Final answer: B
