To solve the expression \(-12 - (-6)\), we need to remember that subtracting a negative number is the same as adding its positive counterpart. In other words, \(- (-6)\) is equivalent to \(+ 6\). So the expression becomes:

\[
-12 - (-6) = -12 + 6
\]

Now we add \(-12\) and \(6\):

\[
-12 + 6 = -6
\]

Therefore, the answer is:
A. -6
