The correct option is C

12.12 , 12.34 , 12.45 ,12.54

All the given decimals have 12 as their whole number part. To compare them, we need to compare the fractional parts.

$\begin{array}{ccccc}\text{Decimal}& \text{Tens}& \text{Ones}& \text{Tenths}& \text{Hundredths}\\ 12.34& 1& 2& 3& 4\\ 12.12& 1& 2& 1& 2\\ 12.45& 1& 2& 4& 5\\ 12.54& 1& 2& 5& 4\end{array}$

Greater the number of tenths, greater is the number.

Since 1 < 3 < 4 < 5, we have the asceding order of given decimals as follows:

12.12, 12.34, 12.45, 12.54
