B. Ssorghum
C. China rose
D. Both (1) & (2)

Answer

To determine which of the following plants do not show Kranz anatomy in their leaves, we need to understand what Kranz anatomy is and which plants exhibit it.

**Step 1: Understand Kranz Anatomy**
Kranz anatomy is a specialized structure found in the leaves of C4 plants. In these plants, there are two types of cells involved in photosynthesis: mesophyll cells and bundle sheath cells. The mesophyll cells are located around the bundle sheath cells, which helps in the efficient fixation of carbon dioxide.

**Step 2: Analyze the Options**
- **Maize (Mace)**: Maize is a well-known C4 plant that exhibits Kranz anatomy due to its specialized leaf structure.
- **Sorghum**: Sorghum is also a C4 plant and shows Kranz anatomy.
- **China Rose**: China Rose (Hibiscus rosa-sinensis) is not a C4 plant; it is a C3 plant and does not exhibit Kranz anatomy.

**Step 3: Identify the Correct Answer**
From the analysis:
- Maize and Sorghum show Kranz anatomy.
- China Rose does not show Kranz anatomy.

Therefore, the correct answer to the question "Which of the following do not show Kranz anatomy in their leaves?" is **China Rose**.

**Final Answer: China Rose**
