Final answer:
The most accurate depiction of the limitations of the ABC system is that it is costly to implement, making it the primary limitation mentioned. The system is complex and resource-intensive, which negates the simplicity and ease of implementation that other options suggest.
Step-by-step explanation:
Limitations of the ABC system include several factors, but primarily it is known for being a more complex and expensive approach to overhead cost allocation compared to traditional costing methods. A key limitation is that Activity-Based Costing (ABC) is very costly to implement, making answer (a) correct. It requires significant resources to maintain and can involve complex data analysis. The notion that managers prefer it due to simplicity, as suggested in option (c), is typically incorrect. Managers may find that ABC provides detailed insights into cost drivers and can aid in strategic decision-making, yet its complexity is generally not viewed as a benefit. ABC is also not necessarily easier to implement than traditional costing methods, which negates option (b) as a correct answer. Considering the options provided, ABC system's limitations do not align with ease of implementation or manager enjoyment due to simplicity, which supports that answer (d) 'None of the above' is inaccurate since (a) is indeed a known limitation of ABC.
