Answer:
The correct option is C. Spine is present on the posterior surface of the scapula
Explanation:
The scapula is a triangular bone that joins humerus with the clavicle.

The nuclear envelope, also known as the nuclear membrane, [a] is made up of two lipid bilayer membranes which in eukaryotic cells surrounds the nucleus, which encases the genetic material. The nuclear envelope consists of two lipid bilayer membranes, an inner nuclear membrane, and an outer nuclear membrane. The space between the membranes is called the perinuclear space.
