• C. $13$ to $18$
• D. Element lying at the bottom of periodic table

Answer 1

Answer: (A), (C)

$1$ and $2$
$13$ to $18$

Representative elements are the elements within the first two groups $1$ and $2$ and last six groups on the right side of periodic table $13-18$. They do not exhibit variable valencies. They are metals, non-metals and metalloids.

Hence, the correct options are $\text{A}$ and $\text{C}$
