NEET 2025 Chemistry question on Redox and Electrochemistry

If the molar conductivity ($\Lambda_m$) of a 0.050 mol L$^{-1}$ solution of a monobasic weak acid is 90 S cm$^2$ mol$^{-1}$, its extent (degree) of dissociation will be

[Assume $\lambda^+$ = 349.6 S cm$^2$ mol$^{-1}$ and $\lambda^-$ = 50.4 S cm$^2$ mol$^{-1}$.]
