Asilver and gold. Both silver and gold are elements. b is not correct because CO2 is a compound, not a mixture, and c is incorrect because salt and pepper are not elements.

Elements are pure substances that are found on the periodic table. 

Pepper is NOT an element. 
Carbon dioxide is a compound, not mixture. 
Next, gold and silver are both elements, so that may be the answer!

Answer: a) silver and gold
