Verified step by step guidance

Understand the question: The problem is asking which procedure uses a device with a light attached to look inside a body cavity or organ. This requires knowledge of medical diagnostic tools and their functions.
Step 1: Define the term 'endoscopy.' An endoscopy is a medical procedure that involves inserting a flexible tube with a light and camera (called an endoscope) into the body to visually examine internal organs or cavities.
Step 2: Compare the other options: MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to create detailed images of the body, but it does not involve a light or direct visualization. Ultrasound uses sound waves to create images of internal structures, and a biopsy involves taking a tissue sample for analysis. Neither of these uses a light to look inside the body.
Step 3: Identify the correct answer: Based on the definitions, the procedure that uses a device with a light to look inside a body cavity or organ is an endoscopy.
Step 4: Conclude: The correct answer is 'Endoscopy,' as it matches the description provided in the question.
