[NEET 2023]

a

\(\sigma 1\mathrm{s}<{\sigma }^{*}1\mathrm{s}<\sigma 2\mathrm{s}<{\sigma }^{*}2\mathrm{s}<\sigma 2{\mathrm{p}}_{\mathrm{z}}<\\ \left(\pi 2{\mathrm{p}}_{\mathrm{x}}=\pi 2{\mathrm{p}}_{\mathrm{y}}\right)<\left({\pi }^{*}2{\mathrm{p}}_{\mathrm{x}}={\pi }^{*}2{\mathrm{p}}_{\mathrm{y}}\right)<{\sigma }^{*}2{\mathrm{p}}_{\mathrm{z}}\)

b

\(\sigma 1\mathrm{s}<{\sigma }^{*}1\mathrm{s}<\sigma 2\mathrm{s}<{\sigma }^{*}2\mathrm{s}<\sigma 2{\mathrm{p}}_{\mathrm{z}}<\\ {\sigma }^{*}2{\mathrm{p}}_{\mathrm{z}}<\left(\pi 2{\mathrm{p}}_{\mathrm{x}}=\pi 2{\mathrm{p}}_{\mathrm{y}}\right)<\left({\pi }^{*}2{\mathrm{p}}_{\mathrm{x}}={\pi }^{*}2{\mathrm{p}}_{\mathrm{y}}\right)\)

c

\(\sigma 1\mathrm{s}<{\sigma }^{*}1\mathrm{s}<\sigma 2\mathrm{s}<{\sigma }^{*}2\mathrm{s}<\left(\pi 2{\mathrm{p}}_{\mathrm{x}}=\pi 2{\mathrm{p}}_{\mathrm{y}}\right)<\\ \left({\pi }^{*}2{\mathrm{p}}_{\mathrm{x}}={\pi }^{*}2{\mathrm{p}}_{\mathrm{y}}\right)<\sigma 2{\mathrm{p}}_{\mathrm{z}}<{\sigma }^{*}2{\mathrm{p}}_{\mathrm{z}}\)

d

\(\sigma 1\mathrm{s}<{\sigma }^{*}1\mathrm{s}<\sigma 2\mathrm{s}<{\sigma }^{*}2\mathrm{s}<\left(\pi 2{\mathrm{p}}_{\mathrm{x}}=\pi 2{\mathrm{p}}_{\mathrm{y}}\right)<\\ \sigma 2{\mathrm{p}}_{\mathrm{z}}<\left({\pi }^{*}2{\mathrm{p}}_{\mathrm{x}}={\pi }^{*}2{\mathrm{p}}_{\mathrm{y}}\right)<{\sigma }^{*}2{\mathrm{p}}_{\mathrm{z}}\)
