Solution

The correct options are
C $2 \times 10 + 3 \times 10 + 1$
D $3 \times 100 + 2 \times 100 + 2$
The general form of any three digit number is, $a b c = a \times 100 + b \times 10 + c$
Here, $2 \times 10 + 3 \times 10 + 1$ and $3 \times 100 + 2 \times 100 + 2$ are not in generalised form
So, options B and C are correct.
