Answer 1

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 $\text{copper-nickel}$. 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 $\text{E}$ is a wrong statement.
