If \( C_{1} \equiv y=\frac{1}{1+x^{2}} \) and \( C_{2} \equiv y=\frac{x^{2}}{2} \) be two curve
P lying in XY plane. Then

WV
(a) area bounded by curve \( \mathrm{C}_{1} \) and \( \mathrm{y}=0 \) is \( \pi \)
(b) area bounded by \( \mathrm{C}_{1} \) and \( \mathrm{C}_{2} \) is \( \frac{\pi}{2}-\frac{1}{3} \)
(c) area bounded by \( \mathrm{C}_{1} \) and \( \mathrm{C}_{2} \) is \( 1-\frac{\pi}{2} \)
(d) area bounded by curve \( \mathrm{C}_{1} \) and \( \mathrm{x} \)-axis is \( \frac{\pi}{2} \)
