Protective membrane that surrounds the nucleus:
A
Chromatin
B
Vesicles
C
Centrioles
D
Nuclear Envelope
Explanation: 

Detailed explanation-1: -The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum.

Detailed explanation-2: -The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.

Detailed explanation-3: -In eukaryotic cells, the membrane that surrounds the nucleus-commonly called the nuclear envelope-partitions this DNA from the cell’s protein synthesis machinery, which is located in the cytoplasm.

Detailed explanation-4: -The nuclear membrane, also called the nuclear envelope, is a double membrane layer that separates the contents of the nucleus from the rest of the cell. It is found in both animal and plant cells. A cell has many jobs, such as building proteins, converting molecules into energy, and removing waste products.

Detailed explanation-5: -The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope. The nuclear envelope isolates and protects a cell’s DNA from various molecules that could accidentally damage its structure or interfere with its processing.
