Solution

The correct option is A Carat

The transparency of gold is measured in carats. The purest gold has a assess of 24 carats. It indicates that there is no other metal diverse with the gold. As the cartage of gold reduces, it indicates the survival of other metals, usually copper and silver, mixed with gold.

For example, 18-carat gold has 75% (18/24) of gold and 25% of other metals. Another way of denoting the transparency of gold is by the fineness.

Thus, the correct option is A.
