For a particle of mass $m$ confined in a rectangular box with sides 2 a and a , the energy and degeneracy of the first excited state, respectively, are
(a)$\frac{\mathrm{h}^{2}}{8 \mathrm{m}}\left(\frac{2}{\mathrm{a}^{2}}\right), 1$
(b)$\frac{\mathrm{h}^{2}}{8 \mathrm{m}}\left(\frac{17}{4 \mathrm{a}^{2}}\right), 2$
(c)$\frac{\mathrm{h}^{2}}{8 \mathrm{m}}\left(\frac{5}{4 \mathrm{a}^{2}}\right), 1$
(d)$\frac{\mathrm{h}^{2}}{8 \mathrm{m}}\left(\frac{5}{\mathrm{a}^{2}}\right), 2$
