(b) The correct statements based on the given information about the cerebral cortex is (2); the grey matter of the cerebral cortex is due to the presence of neuron cell bodies.
The other statements (A), (C) and (d) are incorrect because The cerebral cortex is responsible for a wide range of functions, including sensory perception, motor functions, memory, language, and higher-order cognitive processes.
The association areas of the cerebral cortex are involved in complex and higher-order cognitive functions, such as problem-solving, decision-making, and integrating sensory information.
The cerebral cortex is highly folded and convoluted, forming ridges (gyri) and grooves (sulci). This folding increases the surface area of the cortex, allowing for a greater number of neurons and functional areas within a limited space.
