Concept:
Bones in the human body are classified according to their shape and structure. Common classifications include:
• Long bones
• Short bones
• Flat bones
• Irregular bones
• Sesamoid bones
Fibrous bone and condyloid bone are not standard classifications of bones by shape.
Step 1: Identify valid bone classifications.
Among the given options:
\[
\text{Long bone, Flat bone, and Sesamoid bone}
\]
are recognized categories of bones.
Step 2: Eliminate incorrect classifications.
• Fibrous bone is not a standard structural classification of bones.
• Condyloid refers to a type of joint, not a bone classification.
Step 3: Choose the correct combination.
Thus, the correct set is:
\[
A, C, D
\]
Hence, the correct answer is:
\[
\boxed{(C)\ A, C, D\ \text{only}}
\]
