mp T3 → solid liquid, bpT4 → liquid-gas Critical point T2, triple point T1→ solid liquid gas

Q. Observe the P-T phase diagrams for a given substance $A$ . Then melting point of $A (s)$ , boiling point of $A (l)$ , critical point of $A$ and triple point of $A$ (at their respective pressures) are respectively -

$T_{1}, T_{2}, T_{3}, T_{4}$

$T_{4}, T_{3}, T_{1}, T_{2}$

$T_{3}, T_{4}, T_{2}, T_{1}$

$T_{2}, T_{1}, T_{3}, T_{4}$

$m p T_{3} \to$ solid & liquid, $b p T_{4} \to$ liquid-gas
Critical point $T_{2}$ , triple point $T_{1} \to$ solid liquid gas

Q. Observe the P-T phase diagrams for a given substance A. Then melting point of A(s), boiling point of A(l), critical point of A and triple point of A (at their respective pressures) are respectively -
