A. जब छोटा हैंडल व्यक्ति को झुकने पर मजबूर करे / When a short handle forces the person to bend
B. जब व्यक्ति को कोई असुविधा न हो / When the person has no discomfort
C. जब झाड़ू केवल सजावट के लिए हो / When broom is only for decoration
D. जब फर्श सूखा हो / When floor is dry

Correct Answer:
A. जब छोटा हैंडल व्यक्ति को झुकने पर मजबूर करे / When a short handle forces the person to bend

Explanation Hindi:
सही लंबाई का हैंडल झुकाव और पीठ तनाव कम करता है। परीक्षा में tool length को body posture से जोड़ें।
