Solid angle is given by area subtended divided by r2-x3A9-x394-Sr2Now- area subtended by a sphere is the whole surface area of sphere-4-x3C0-r2-x27F9-x3A9-4-x3C0-r2r2-x27F9-x3A9-4-x3C0-Answer-E-

The total solid angle subtended by the sphere is
$0.25 π$
$1 π$
$2 π$
$4 π$
$0.5 π$

Solid angle is given by area subtended divided by $r^{2}$ .

$Ω = \frac{Δ S}{r^{2}}$

Now, area subtended by a sphere is the whole surface area of sphere= $4 π r^{2}$

$⟹ Ω = \frac{4 π r^{2}}{r^{2}}$

$⟹ Ω = 4 π$
