Which of the following statements accurately describes perceptual and motor development in preschool-aged children?

Explanation

Option A is correct because by the time children reach 2 years old, most have started walking independently and can manipulate objects without help. Option B is partially true but less precise, as 3-year-olds are typically mobile but can often run. Option C is incorrect since 3-year-olds do not have the same agility as 5-year-olds. Option D is inaccurate because skills like throwing, catching, jumping, and hopping usually begin to appear earlier than 7 to 8 years.
