Area enclosed by curve \( y=f(x) \) and \( y=x^{2}+2 \) between the abscissa \( x=2 \) and \( x=\alpha, \alpha2 \) is given as \( \left(\alpha^{3}-4 \alpha^{2}+8\right) \) sq. unit.
P It is known that curve \( \mathrm{y}=\mathrm{f}(\mathrm{x}) \) lies below the parabola \( \mathrm{y}=\mathrm{x}^{2}+2 \).

W \( f(x) \) lies above \( x \)-axis in \( x \in(p, q) \), then \( (q+p) \) is equal to
(a) 2
(b) 3
(c) 4
