| List-$I$ | List-$II$ |
|---|---|
| $(A)$ यदि $A$ कोटि $3$ का एक व्युत्क्रमणीय (non-singular) आव्यूह है और $|A|=a$,तो $|\text{adj}(A)|=$ | $(I)$ शून्य आव्यूह |
| $(B)$ $A$ कोटि $3$ का एक व्युत्क्रमणीय आव्यूह है और $B$ कोटि $3$ का कोई ऐसा आव्यूह है कि $AB=O$,तो $B$ है | $(II)$ $a^2$ |
| $(C)$ $\begin{vmatrix} 1 & x & x^2 \\ \cos(a-b)y & \cos ay & \cos(a+b)y \\ \sin(a-b)y & \sin ay & \sin(a+b)y \end{vmatrix}$ किस पर निर्भर नहीं करता है | $(III)$ $b$ |
| $(D)$ $A$ कोटि $3$ का एक वर्ग आव्यूह है और $B=A-A^T$,तो $B$ है | $(IV)$ $a$ |
| $(V)$ $0$ |
