Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.

There are only four parts of skill related fitness in the options; they are:
Speed
Agility
Balance
Coordination
Explanation:
Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.
However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:
- Speed: This refers to the ability to run a distance in a short time frame.
- Agility: This is the ability to move easily and quickly in different directions
- Balance: The ability to maintain an upright body position during training or physical activity
- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.
Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
