{'blood pressure': [5, 0, 0, 0], 'barometer': [0, 0, 0, 2], 'thermometer': [2, 0, 1, 2], 'sphygmanometer': [1, 0, 0, 0], 'hydrometer': [0, 0, 0, 1]}

The correct answer is option 2: Sphygmomanometer. Blood pressure is not measured using a barometer (option 1), which is a device used to measure atmospheric pressure. A hydrometer (option 3) is used to measure the specific gravity of a liquid and is not used for measuring blood pressure. Similarly, a thermometer (option 4) is used to measure temperature and is not suitable for measuring blood pressure. On the other hand, a sphygmomanometer is specifically designed for measuring blood pressure. It consists of an inflatable cuff that is placed around the upper arm and a pressure gauge or a mercury column that indicates the pressure in millimeters of mercury (mmHg). By inflating and deflating the cuff and listening for the sounds of the blood flow through the artery, blood pressure can be accurately determined.
