• C. Sorting objects based on texture

Answer: (B)

The term 'seriation' in child development refers to the cognitive ability to arrange objects in a sequential order based on specific attributes, such as size, shape, or other measurable characteristics. This skill is crucial for children as it reflects their understanding of relationships and sequences, which are foundational concepts in mathematics and logical reasoning. Mastering seriation helps children make sense of the world around them, as they learn to organize their experiences and observations systematically. This ability often begins to develop in early childhood and is an important milestone in cognitive development that facilitates further learning and problem-solving skills.
