| List-I (Theory proposed) |
List-II (Author/formula) |
| (A) Textural triangle |
(I) Sorenson |
| (B) Ideal gas |
(II) Schofield |
| (C) pH |
(III) Whitney |
| (D) pF |
(IV) PV = nRT |
Textural triangle → proposed by Whitney → (III)
Ideal gas law → PV = nRT → (IV)
pH → introduced by Sorenson → (I)
pF (logarithmic measure of soil moisture tension) → by Schofield → (II)
Thus, correct matching is: A–III, B–IV, C–I, D–II
