Cognitive Development involves:

• A. Intellectual or mental abilities, including processing and organizing information
• B. Physical growth only
• C. Language expression exclusively
• D. Attachment to caregivers

Answer: (A)

Cognitive development is the growth of thinking skills—how children process, store, retrieve, and use information. It includes reasoning, problem solving, memory, attention, and the ability to organize ideas and plan actions. This is why the description focusing on intellectual or mental abilities and information processing fits best. Other aspects describe different areas: physical growth covers body size and motor development; language development centers on how children express and understand words and sentences; attachment to caregivers relates to social-emotional bonds. For example, when a child sorts objects, follows multi-step directions, or recalls where something belongs, that shows cognitive development in action.
