Detailed Solution

Concept- Gold is a chemical element whose atomic number is 79. Gold in pure form is bright yellow in appearance. Due to its unreactive nature, gold is used in making ornaments and jewellery.
The ornamental gold is a mixture of gold and copper metal. The ratio of the gold and copper metal in the ornamental gold is uniform throughout the composition which means that the copper and gold are mixed so well with each other they cannot be distinguished by the naked eye. Therefore, the ornamental gold is considered a homogeneous mixture.
Hence, the correct answer is option (1).
