The magnitude of vector $\overrightarrow{\mathrm{A}},\overrightarrow{\mathrm{B}}\mathrm{and}\overrightarrow{\mathrm{C}}$ are respectively 12, 5 and 13 units and $\overrightarrow{\mathrm{A}}+\overrightarrow{\mathrm{B}}=\overrightarrow{\mathrm{C}}$ then the angle between $\overrightarrow{\mathrm{A}}\mathrm{and}\overrightarrow{\mathrm{B}}$

 

 

• A

  0

• B

  $\mathrm{\pi }$

• C

  $\frac{\mathrm{\pi }}{2}$

• D
