Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Equisetum is placed in the class Sphenopsida. Reason (R): Equisetum produces two types of spores, macro and micro spores. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Assertion (A) is true because Equisetum is indeed classified under the class Sphenopsida of pteridophytes. Reason (R) is false because Equisetum is a homosporous pteridophyte (produces only one kind of spores). In pteridophytes, heterospory (production of macro and micro spores) is seen in genera like Selaginella and Salvinia. Answer: Assertion (A) is true but Reason (R) is false
