2. Given the following two propositions:
(1) Let $a, b, c$ be complex numbers. If $a^{2}+b^{2}>c^{2}$, then $a^{2}+b^{2}-c^{2}>0$;
(2) Let $a, b, c$ be complex numbers. If $a^{2}+b^{2}-c^{2}>0$, then $a^{2}+b^{2}>c^{2}$.
Then, the correct statement is
A. Proposition (1) is correct, Proposition (2) is also correct
B. Proposition (1) is correct, Proposition (2) is incorrect
C. Proposition (1) is incorrect, Proposition (2) is also incorrect
D. Proposition (1) is incorrect, Proposition (2) is correct
$a^{2}+b^{2}>c^{2} \Rightarrow a^{2}+b^{2}, c^{2}$ are real numbers $\Rightarrow a^{2}+b^{2}-c^{2}>0$, proposition (1) is correct; $a^{2}+b^{2}-c^{2}>0 \Rightarrow a^{2}+b^{2}-c^{2}$ is a real number $\nRightarrow a^{2}+b^{2}>c^{2}$, proposition (2) is incorrect. Therefore, the answer is $B$.
