Final answer:
Without a specific reference to workplace health and safety guidelines or dress code policies, it is not possible to give an accurate answer to the question on the minimum overlap between a coat and trousers for a 90-degree bend. so, option B is the correct answer.
Step-by-step explanation:
The question seems to be related to occupational health and safety, specifically regarding the appropriate dress or uniform standards required for certain work environments. The minimum overlap between a coat and trousers when a person bends over at a 90-degree angle would be specified in workplace health and safety guidelines or dress code policies. However, without a specific reference to such a standard or policy, and as the intervals provided seem unrelated to the question, it is not possible to give an accurate answer to this question.
In real-life settings, the requirements might be dependent on the professionalism expected in certain occupations, the need for protective clothing in industrial environments, or simply to maintain decorum in a workplace. Therefore, the precise measurement would typically be defined by the company policy or industry standards rather than being a universally fixed measurement.
