In a region of free space, the electric field at some instant of time is $\overrightarrow{\mathrm{E}}=(80\widehat{\mathrm{i}}+32\widehat{\mathrm{j}}-64\widehat{\mathrm{k}})\frac{\mathrm{V}}{\mathrm{m}}$ and the magnetic field is $\overrightarrow{\mathrm{B}}=(0.2\widehat{\mathrm{i}}+0.08\widehat{\mathrm{j}}-0.29\widehat{\mathrm{k}})\mathrm{\mu T}$. The pointing vector for these fields is

• A

  $-11.52\widehat{\mathrm{i}}+28.8\widehat{\mathrm{j}}$

• B

  $-28.8\widehat{\mathrm{i}}+11.52\widehat{\mathrm{j}}$

• C

  $28.8\widehat{\mathrm{i}}-11.52\widehat{\mathrm{j}}$

• D

  $11.52\widehat{\mathrm{i}}-28.8\widehat{\mathrm{j}}$
