Dear student.
The correct answer is b. Ligule.
Plants which produce two different types of spores; smaller microspores and larger megaspores are known as Heterospory or Heterosporous.
Heterospory and seed habitat were first originated in Pteridophytes, eg: Selaginella. This sort of plant possesses a membranous scale on the inner side of the leaf sheath, known as ligule.
