Eyes and ears (choice C) are sensory organs that transmit information to the brain but are not part of the central nervous system. The autonomic nervous system (choice D) is a division of the peripheral nervous system responsible for involuntary bodily functions.

Correct Answer: B

Rationale: The correct answer is B: Assistive device. Assistive devices are designed to help disabled individuals perform daily tasks independently. They can range from simple tools to complex technology. Orthotic devices (A) provide support or correct alignment, not necessarily for daily tasks. Restorative devices (C) aim to restore function rather than assist in daily living. Range of motion devices (D) focus on improving mobility, not specifically aiding in daily activities. Therefore, B is the best choice for devices that facilitate activities of daily living for disabled individuals.

Correct Answer: C

Rationale: The correct answer is C: Bereavement. Bereavement refers to the period of time following a loss during which mourning occurs. It is a natural process of grieving and adjusting to the loss.

Burnout (B) is a state of emotional, physical, and mental exhaustion due to prolonged stress or overwork. Blackout (D) refers to a loss of consciousness or memory, not related to mourning. Therefore, C is the correct answer as it specifically relates to the period of mourning following a loss.
