In linear variation method using two orthogonal basis functions, the two roots obtained are $\epsilon_{0}$ and $\epsilon_{1}$ ($\epsilon_{0}<\epsilon_{1}$). The correct relation of these with exact ground and first excited state energies, $E_{0}$ and $E_{1}$, respectively, is
(a)$\epsilon_{0} \geq E_{0}$ and $\epsilon_{1}<E_{1}$
(b)$\epsilon_{0}<E_{1}$ and $\epsilon_{1} \geq E_{1}$
(c)$\epsilon_{0}<E_{0}$ and $\epsilon_{1}<E_{1}$
(d)$\epsilon_{0} \geq E_{0}$ and $\epsilon_{1} \geq E_{1}$
