Answer 1

The correct option is D (i) and (iii)​

● Gold and silver are inert metals (noble metals). Thus, they do not react with water. Thus the given statement is correct.
● Potassium and sodium react violently with cold water. But magnesium does not react with cold water. Thus the given statement is incorrect.
● Aluminium, zinc and iron do not react with hot water but react with steam. Thus the given statement is correct.
● So, statements (i) and (iii) are correct statements.
