Given below are two statements: Statement I: Soluble sources of Ca are gypsum and phosphogypsum. Statement II: Gypsum is used for reclamation of sodic soil.
Choose the most appropriate answer from the options given below:

Correct option is A

· Gypsum and Phosphogypsum: Both are soluble sources of calcium and are widely used in agriculture.
· Gypsum for Reclamation: Gypsum is effectively used for the reclamation of sodic soils by replacing sodium ions with calcium ions, thereby improving soil structure and reducing alkalinity.
· Therefore, both statements are true.
Thus, the correct answer is (a) Both Statement I and Statement II are correct.
