What term refers to a physical developmental milestone that involves sitting up unsupported?

Crawling
Locomotion
Cruising
Postural stability

The correct answer is: Postural stability

Postural stability involves the ability to sit up unsupported, and is an important physical developmental milestone for infants. Crawling and locomotion are considered early motor skills and do not necessarily require sitting up unsupported. Cruising, on the other hand, involves a child using furniture or objects to support themselves while standing and walking, which is a more advanced milestone after acquiring postural stability.
