The correct answer is option 3: optical fibre. An endoscope is a medical instrument used to detect ulcers in the stomach. It consists of a long and narrow tube with a small glowing bulb at one end. This tube is inserted into the stomach through the mouth. The tube contains an optical fibre, which is a thin, flexible cable made of transparent glass. The optical fibre is used to transmit light from the bulb to the area being examined. It allows the doctor to view the internal organs and identify any ulcers or abnormalities. This method is minimally invasive and provides a clear view of the stomach without the need for open surgery. The other options, such as a small current carrying wire or a narrow tube containing water or chemical solution, are not accurate for the purpose of detecting ulcers.
