A and B are two vectors given by  $\mathbf{A}=2\hat{\mathbf{i}}+3\hat{\mathbf{j}}$ and $\mathbf{B}=2\hat{\mathbf{i}}+4\hat{\mathbf{j}}$ . The magnitude of the' component of A
along B is

• A

  $\frac{5}{\sqrt{2}}$

• B

  $\frac{3}{\sqrt{2}}$

• C

  $\frac{8}{\sqrt{5}}$

• D

  $\frac{5}{\sqrt{13}}$
