• A. Strobili $ \rightarrow $ Sporophylls $ \rightarrow $ Sporangia $ \rightarrow $ Spores
• B. Strobili $ \rightarrow $ Sporangia $ \rightarrow $ Sporophylls $ \rightarrow $ Spores
• C. Sporophylls $ \rightarrow $ Strobili $ \rightarrow $ Sporangia $ \rightarrow $ Spores
• D. Spores $ \rightarrow $ Sporangia $ \rightarrow $ Strobili $ \rightarrow \, $ Cones

Answer 1

Answer: (A)

Spore producing modified leaves are called sporophyll, which are organized around an axis is spirally to found a compact structure called strobili. Each sporophyll bears sac-like structure called sporangia and inside it spore mother cell undergoes meiosis to form haploid spores.
