Both A and R are true but R is not correct explanation of A
A is true but R is false
A and R are false
Correct Answer
Detailed Explanation
Algin is a polysaccharide derived from brown algae, making the assertion true. The reason provided, that rust of wheat is caused by the fungus Puccinia, is also accurate; however, it does not explain the assertion about algin. Option B is incorrect because, while both statements are true, they are unrelated. Options C and D are incorrect as they misrepresent the truth of both statements. Understanding the sources of algin and the pathogens affecting crops is essential in botany and plant pathology.
