Let \( P \) be a \( 3 \times 3 \) non-null real matrix. If there exist a \( 3 \times 2 \) real matrix \( Q \) and a \( 2 \times 3 \) real matrix \( R \) such that \( P=Q R \), then (A) \( P x=0 \) has a unique solution, where \( 0 \in \mathbb{R}^{3} \) (B) there exists \( \boldsymbol{b} \in \mathbb{R}^{3} \) such that \( P \boldsymbol{x}=\boldsymbol{b} \) has no solution (C) there exists a non-zero \( b \in \mathbb{R}^{3} \) such that \( P x=b \) has a unique solution (D) there exists a non-zero \( \boldsymbol{b} \in \mathbb{R}^{3} \) such that \( P^{T} \boldsymbol{x}=\boldsymbol{b} \) has a unique solution
