Quizplus · Accepted Answer

The fact that most children learn to walk and talk at a similar age despite individual differences in upbringing and environment points to maturation - the internally programmed, biological schedule of development.

Thus, choice (C) - maturation - is the best answer. Choices (A) heredity, (B) environmental influences, and (D) a critical period, are not as directly relevant to this specific example of developmental timing in walking and talking.
