Official Solution & Explanation:
Correct Answer: Option B(24)
विशुद्ध सोना 24 कैरेट (100% शुद्धता) का होता है। 24 कैरेट सोना अत्यधिक मुलायम होने के कारण आभूषण निर्माण हेतु इसमें तांबा या चांदी मिलाकर 22 या 18 कैरेट में ढाला जाता है।
Pure gold is 24 carats (99.9% fine gold). It is alloyed with copper or silver to make 22 or 18 carat gold for jewelry making.
