The correct Answer is:
To solve the question, we need to evaluate each of the four statements provided and determine which ones are correct or incorrect. **Step 1: Analyze Statement A** - Statement A: "The sporophyte in liverworts is more elaborate than that in mosses." - **Evaluation**: In bryophytes, liverworts have a less complex sporophyte compared to mosses. Therefore, this statement is **incorrect**. **Step 2: Analyze Statement B** - Statement B: "Salvinia is heterosporous." - **Evaluation**: Salvinia is indeed a heterosporous plant, meaning it produces two different types of spores (microspores and megaspores). Thus, this statement is **correct**. **Step 3: Analyze Statement C** - Statement C: "The life cycle in all seed-bearing plants is diplontic." - **Evaluation**: Seed-bearing plants (angiosperms and gymnosperms) exhibit a diplontic life cycle, where the dominant phase is the diploid sporophyte. Hence, this statement is **correct**. **Step 4: Analyze Statement D** - Statement D: "In Pinus, male and female cones are borne on different trees." - **Evaluation**: In Pinus (a type of gymnosperm), both male and female cones are produced on the same tree. Therefore, this statement is **incorrect**. **Conclusion**: The two incorrect statements are A and D. **Final Answer**: The two wrong statements together are A and D. ---
