Study the following lists
`{:("List-I",,"List-II"),("A. Endothecium",,"I. present between the pollen sacs"),("B.Tapetum",,"II. Fibrous thickenings"),("C.Stomium",,"III. Outer layer of microsporangium"),("D. Sporogenous tissue ",,"IV. Nourishes the pollen grains"),("",,"V. Centre of microsporangium"):}`

Options

A. `{:(A,,B,,C,,D),(IV,,I,,III,,II):}`
B. `{:(A,,B,,C,,D),(II,,IV,,I,,V):}`
C. `{:(A,,B,,C,,D),(I,,II,,III,,V):}`
D. `{:(A,,B,,C,,D),(IV,,V,,I,,II):}`

Answer

To solve the question, we need to match the items in List-I with their corresponding items in List-II based on their definitions and roles in the structure of the anther. Here’s the step-by-step solution:

### Step 1: Understand the components of List-I
- **A. Endothecium**: This is a layer of cells in the anther that has fibrous thickenings.
- **B. Tapetum**: This layer provides nourishment to the developing pollen grains.
- **C. Stomium**: This is the region that is present between the pollen sacs, facilitating the opening of the anther.
- **D. Sporogenous tissue**: This tissue is located at the center of the microsporangium and is responsible for producing microspores.

### Step 2: Match List-I with List-II
Now we will match each component from List-I with the correct description from List-II:

1. **Endothecium (A)**: This corresponds to **II. Fibrous thickenings**.
2. **Tapetum (B)**: This corresponds to **IV. Nourishes the pollen grains**.
3. **Stomium (C)**: This corresponds to **I. Present between the pollen sacs**.
4. **Sporogenous tissue (D)**: This corresponds to **V. Centre of microsporangium**.

### Step 3: Write down the final matches
Based on the above analysis, we can summarize the matches as follows:
- A → II (Endothecium → Fibrous thickenings)
- B → IV (Tapetum → Nourishes the pollen grains)
- C → I (Stomium → Present between the pollen sacs)
- D → V (Sporogenous tissue → Centre of microsporangium)

### Final Matches:
- A: II
- B: IV
- C: I
- D: V
