Quizplus · Accepted Answer

18 karat gold contains 75% gold, which means that out of 100 parts, 75 parts are pure gold and the remaining 25 parts are other metals such as silver, copper, and zinc. Therefore, option D is correct. Option A is incorrect because 18 karat gold is not made up of only 18% gold. Options B and C are also incorrect as they do not reflect the actual percentage of gold in 18 karat gold. The last option is not a valid percentage.
