If \( \sec \alpha, \tan \alpha \) are roots of \( a^{2}+b x+c=0 \), then
(a) \( \mathrm{a}^{4}-\mathrm{b}^{4}+4 \mathrm{ab}^{2} \mathrm{c}=0 \)
(b) \( \mathrm{a}^{4}+\mathrm{b}^{4}-4 \mathrm{ab}^{2} \mathrm{c}=0 \)
P
(c) \( \mathrm{a}^{2}-\mathrm{b}^{2}=4 \mathrm{ac} \)
(d) \( \mathrm{a}^{2}+\mathrm{b}^{2}=\mathrm{ac} \)
