Correct Answer
Detailed Explanation
Option C is correct because the assertion that H₃PO₄ and H₃PO₃ are present in fertilizers for plant protection is true, while the reason stating that H₃PO₃ does not increase the solubility of fertilizers is false; in fact, H₃PO₃ can enhance nutrient availability. Option A is incorrect because, although both statements are true, the reason does not correctly explain the assertion. Option B is incorrect as it claims both statements are true but does not link them appropriately. Option D is incorrect because the assertion is indeed true.
