In an electromagnetic wave, the electric and magnetising fields are $100 \mathrm{V} {\mathrm{m}}^{-1}$ and $0.265 \mathrm{A} {\mathrm{m}}^{-1}$. The maximum energy flow is 

• A

  $26.5 \mathrm{W}/{\mathrm{m}}^2$

• B

  $36.5 \mathrm{W}/{\mathrm{m}}^2$

• C

  $46.7 \mathrm{W}/{\mathrm{m}}^2$

• D

  $765 \mathrm{W}/{\mathrm{m}}^2$
