Q. The graph, shown in the diagram, represents the variation of temperature (T) of the bodies, x and y having same surface area, with time (t) due to the emission of radiation. Find the correct relation between the emissivity and absorptivity power of the two bodies

$E_{x} > E_{y} a n d a_{x} < a_{y}$
$E_{x} < E_{y} a n d a_{x} > a_{y}$
$E_{x} > E_{y} a n d a_{x} > a_{y}$
$E_{x} < E_{y} a n d a_{x} < a_{y}$
