250 mL of a waste solution obtained from the workshop of a goldsmith contains `0.1MAgNO_(3)` and `0.1MAuCl`. The solution was electrolyzed at 2 V by passing a current of 1 A for 15 minutes. The metal/metals electrodeposited will be :
`(E_(Ag^(+)//Ag)^(@)=0.80V, E_(Au^(+)//Au)^(@)=1.69V)`

A

silver and gold in equal mass proportion

B

only gold

C

only silver

D

silver and gold in proportion to their atomic weights
