Correct answer: B
Solution
(b) In gymnosperms like Cedrus, the male and female gametophytes are highly reduced and dependent on the sporophyte, so they do not have a free-living independent existence.• Polytrichum and Funaria → bryophytes → gametophyte is free-living and dominant
• Pteris → pteridophyte → gametophyte (prothallus) is free-living
• Cedrus → gymnosperm → gametophyte is dependent
