Solution

The correct option is E The 'silver' UK coins are made of Ag/Ni alloy
In the U.K., silver-coloured coins minted between 1947 and 2012 were made from copper-nickel. The nickel coin comprises 25 per cent nickel and 75 per cent copper and weighs five grams, according to the U.S. Mint.

Hence, option E is a wrong statement.
