Accepted Answer

Correct Answer: BStep-by-step Solution:Evaluating each option:Equisetum - Homosporous (A): Correct. Equisetum (horsetail) produces a single type of spore (homospory), which develops into a bisexual gametophyte bearing both antheridia and archegonia.Pinus - Dioecious (B): Incorrect. Pinus is monoecious, meaning both male cones (microstrobili, bearing microspores/pollen) and female cones (megastrobili, bearing megaspores/ovules) are present on the same plant. Stating it is dioecious (separate male and female plants) is wrong.Cycas - Dioecious (C): Correct. Cycas is dioecious: male plants bear pollen cones (microsporophylls) and female plants bear megasporophylls, on separate individuals.Salvinia - Heterosporous (D): Correct. Salvinia (aquatic fern) is heterosporous, producing microspores (developing into male gametophytes) and megaspores (developing into female gametophytes) in separate sporangia.Why other options are incorrect:Options A, C, and D are all correctly paired plant characteristics, so they are not the mismatch.Key Concept:Monoecious: Male and female reproductive structures on the same plant (e.g., Pinus, maize, coconut). Dioecious: Male and female on separate plants (e.g., Cycas, Marchantia, date palm, papaya). Homosporous: One type of spore (e.g., most ferns, Equisetum). Heterosporous: Two types of spores (e.g., Selaginella, Salvinia).
