![4. True/False Question: In parts (a) and (b), determine whether the statement is true or false, and justify your answer (i.e., prove it if it is true, and find a counter-example if it is false).
(a) For every square matrices \( A \) and \( B \) of order 3, it holds that
\[
\text{det}(A + B) = \text{det}(A) + \text{det}(B).
\]
(b) For every square matrix \( A \) of order 2 and every scalar \( c \), it holds that
\[
\text{det}(cA) = c^2 \text{det}(A).
