The rectangular surface of area \[8 cm\times 4 cm\]of a black body at temperature \[127{}^\circ C\] emits energy E per second. If the length and breadth are reduced to half of the initial value and the temperature is raised to \[327{}^\circ C\], the rate of emission of energy becomes

• A. \[\frac{3}{8}\operatorname{E}\]
• B. \[\frac{81}{16}\operatorname{E}\]
• C. \[\frac{9}{16}\operatorname{E}\]
• D. \[\frac{81}{64}\operatorname{E}\]
