Answer 1

The correct answer is option (a) Group 11 elements.

• Group 11, with modern IUPAC numbers, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au). Roentgenium (Rg) is also placed in this group on the periodic table, although no chemical tests have been performed to confirm its behavior as a heavy to gold homolog.
• Group 11 is also known as coin metals, due to their use in mining — while rising commodity prices mean that silver and gold are no longer used for circulation, the remaining for bullion, copper remains the common commodity coin. to date, either a coin of copper or a component of cupronickel. [catation needed] It was probably the first three elements found. Copper, silver, and gold all occur naturally in the basic sense.
