Concept:Development follows specific patterns. One pattern is proximodistal, meaning growth moves from the center of the body outward to the limbs.Explanation:The sequence of development is predictable. The proximodistal tendency shows that central body parts (like the trunk) develop before extremities (like fingers). For example, a baby first controls shoulders, then arms, then hands. This matches the idea that development proceeds from the centre outward. The other options are incorrect: development does not go bottom-to-top (that is cephalocaudal), is not unidimensional, and is strongly influenced by environmental factors.Answer:Option A: proceeds from centre of the body in an outward direction.
