Consider the following four statements whether they are correct or wrong.
(A) The sporophyte in liverworts is more elaborate than that in mosses.
(B) Salvinia is heterosporous.
(C ) The life cycle in all seed-bearing plants is diplontic.
(D) In Pinus, male and female cones are borne on different trees.
The two wrong statements together are

Options

A. (B) and (C )
B. (A) and (B)
C. (A) and (C )
D. (A) and (D)

Answer

To determine which two statements among the four provided are incorrect, we will analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A:** The sporophyte in liverworts is more elaborate than that in mosses.

- **Analysis:** This statement is incorrect. In fact, the sporophyte in mosses is generally more complex and developed compared to that in liverworts. Liverworts have a simpler sporophyte structure.

### Step 2: Analyze Statement B
**Statement B:** Salvinia is heterosporous.

- **Analysis:** This statement is correct. Salvinia is indeed a heterosporous plant, which means it produces two different types of spores: microspores and megaspores.

### Step 3: Analyze Statement C
**Statement C:** The life cycle in all seed-bearing plants is diplontic.

- **Analysis:** This statement is incorrect. While many seed-bearing plants exhibit a diplontic life cycle, not all do. For example, some plants may have variations in their life cycles, such as certain gymnosperms and angiosperms.

### Step 4: Analyze Statement D
**Statement D:** In Pinus, male and female cones are borne on different trees.

- **Analysis:** This statement is incorrect. In Pinus, which is a gymnosperm, male and female cones are typically found on the same tree but on different branches. Therefore, this statement is not accurate.

### Conclusion
Based on the analysis:
- **Incorrect Statements:** A (The sporophyte in liverworts is more elaborate than that in mosses) and C (The life cycle in all seed-bearing plants is diplontic).
- **Correct Statements:** B (Salvinia is heterosporous) and D (In Pinus, male and female cones are borne on different trees).

Thus, the two wrong statements together are **A and C**.
