C
क्रोमियम
Chromium
D

Copper
Correct
Official Solution & Explanation:
Correct Answer: Option D(तांबा)
तांबा (Copper) एक प्रतिचुंबकीय (Diamagnetic) पदार्थ है, जो चुंबकीय क्षेत्र में रखे जाने पर क्षेत्र की विपरीत दिशा में दुर्बल रूप से चुंबकित होता है और चुंबक से प्रतिकर्षित होता है। अतः यह अचुंबकीय है।
Copper is a diamagnetic material, meaning it creates an opposing magnetic field when exposed to an external magnetic field and is weakly repelled, thus behaving as non-magnetic.
