$\vec{A}$ and $\vec{B}$ are two non-zero vectors inclined at an angle $\theta$. $\hat{a}$ and $\hat{b}$ are unit vectors along $\vec{A}$ and $\vec{B}$ respectively. The component of $\vec{A}$ in the direction of $\vec{B}$ is

  • A
    $\vec{A} \cdot \hat{b}$
  • B
    $\frac{\vec{A} \times \vec{B}}{A}$
  • C
    $\hat{a} \cdot \vec{B}$
  • D
    $\vec{A} \cdot \vec{B}$
