Solutions: JEE Main 2026 Chemistry question

Consider a solution of $\mathrm{CO_2(g)}$ dissolved in water in a closed container. Which one of the following plots correctly represents variation of log (partial pressure of $\mathrm{CO_2}$ in vapour phase above water) [$y$-axis] with log (mole fraction of $\mathrm{CO_2}$ in water) [$x$-axis] at $25^\circ\mathrm{C}$?
