Options

  1. ASelaginella
  2. BEquisetum
  3. CSalvinia
  4. DBoth 1 and 3

Correct answer

B. Equisetum

Step-by-step solution

In majority of the pteridophytes, all the spores are of similar kinds; such plants are called homosporous. Equisetum is an example of a homosporous pteridophyte. Genera like Selaginella and Salvinia produce two kinds of spores, macro (large) and micro (small) spores, and are known as heterosporous. Therefore, options 1, 3, and 4 represent heterosporous plants and are incorrect. Answer: Equisetum
