Dense fibrous complex lying adjacent to inner membrane of nuclear envelope is
(A) Chromatin
(B) Fibrous lamina
(C) Nuclear lamina
(D) Both B and C

Options

A. Chromatin
B. Fibrous lamina
C. Nuclear lamina
D. Both B and C

Answer

To solve the question regarding the dense fibrous complex lying adjacent to the inner membrane of the nuclear envelope, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Nuclear Envelope**:
- The nuclear envelope is a double-membraned structure that surrounds the nucleus of a cell. It consists of an outer membrane and an inner membrane.

2. **Identify Components Adjacent to the Inner Membrane**:
- The inner membrane of the nuclear envelope is associated with various structures. One of the key components is the nuclear lamina.

3. **Define Nuclear Lamina**:
- The nuclear lamina is a dense fibrous network composed of intermediate filaments and proteins. It lies adjacent to the inner membrane of the nuclear envelope and provides structural support to the nucleus.

4. **Consider Other Options**:
- The term "fibrous lamina" can also refer to the same structure as the nuclear lamina. Therefore, both terms can be used interchangeably in this context.

5. **Evaluate the Options**:
- (A) Chromatin: This is incorrect as chromatin is the material that makes up chromosomes and is not a fibrous complex adjacent to the nuclear envelope.
- (B) Fibrous lamina: This is correct as it refers to the same structure as the nuclear lamina.
- (C) Nuclear lamina: This is also correct as it is the specific name for the fibrous network adjacent to the inner membrane.
- (D) Both B and C: Since both terms refer to the same structure, this option is also correct.

6. **Select the Correct Answer**:
- The best answer is (D) Both B and C, as both terms describe the dense fibrous complex adjacent to the inner membrane of the nuclear envelope.

### Final Answer:
(D) Both B and C
