E. Hyperactivity

Choose the correct answer from the options given below

Intellectual disability (ID), once called mental retardation, is characterized by below-average intelligence or mental ability and a lack of skills necessary for day-to-day living. People with intellectual disabilities can and do learn new skills, but they learn them more slowly.

 Important Points

•  Intellectual Disability: Intellectual disability means a significantly reduced ability to understand new or complex information and to learn and apply new skills (impaired intelligence).
• This results in a reduced ability to cope independently (impaired social functioning), and begins before adulthood, with a lasting effect on development.
• Cognitive Impairment: Cognitive impairment is when a person has trouble remembering, learning new things, concentrating, or making decisions that affect their everyday life. Cognitive impairment ranges from mild to severe.
• General Learning Disability: A learning disability is a reduced intellectual ability and difficulty with everyday activities, with onset in childhood. NICE states that: 'A learning disability is generally defined by three core criteria:
• Lower intellectual ability (usually an IQ of less than 70).
• Significant impairment of social or adaptive functioning. Onset in childhood.

Additional Information

Articulation  disorder: 

• Hyperactivity: Hyperactive behavior usually refers to constant activity, being easily distracted, impulsiveness, inability to concentrate, aggressiveness, and similar behaviors. Typical behaviors may include: Fidgeting or constant moving

Therefore intellectual, disability, cognitive impairment, and general learning disability are the limitations in intellectual functioning. 

Thus B, C, and D only are correct options.
