Concept:
An egg has a complex internal structure designed to protect and support the central yolk.
• Albumen: The egg white, which provides water and protein.
• Yolk: The central nutrient-rich core.
Step 1: Identifying the Chalazae.
The chalazae are two spiral, rope-like strands of thickened albumen.
They are attached to the top and bottom of the yolk.
Step 2: Understanding the function.
The chalazae act like an anchor to keep the yolk centered within the egg white.
This prevents the yolk from pressing against the shell.
Step 3: Analyzing other parts.
The vitelline membrane is the clear casing that holds the yolk itself.
The cuticle is the outer coating of the shell.
Final Answer: (B)
