A pit present in the wall of cell lying adjacent to an intercellular
space is

Options

A. Complete pit
B. Blind pit
C. A pit without its partner
D. Both B and C

Answer

To solve the question "A pit present in the wall of a cell lying adjacent to an intercellular space is," we need to analyze the options provided and understand the definitions of various types of pits in cell walls.

### Step-by-Step Solution:

1. **Understand the Concept of Pits**:
- Pits are specialized structures in the cell wall that allow for communication between adjacent cells. They are thinner areas of the cell wall.

2. **Identify Types of Pits**:
- **Complete Pits (or Simple Pits)**: These are pits that occur in pairs, meaning there is a complementary pit in the adjacent cell wall. They facilitate communication between two cells.
- **Blind Pits**: These are pits that do not have a complementary pit in the adjacent cell wall. They are present between the cell wall and the intercellular space.

3. **Analyze the Question**:
- The question specifies a pit that is adjacent to an intercellular space. This indicates that the pit does not have a complementary pit in the adjacent cell wall.

4. **Evaluate the Options**:
- **Option A: Complete Pit** - This is incorrect because complete pits are present between two cells and have a partner.
- **Option B: Blind Pit** - This is correct as it describes a pit that lacks a complementary pit.
- **Option C: A Pit Without Its Partner** - This is also correct because it describes the same characteristic as a blind pit.
- **Option D: Both B and C** - Since both options B and C are correct, this is the best choice.

5. **Conclusion**:
- The correct answer to the question is **D: Both B and C**.
