Answer:
Sonogram
Explanation:
A sonogram is a medical diagnostic method that is commonly uses sound waves in order to generate images of any tissues, organs, or some other internal structures inside the human body. This sonogram does not use any kind of harmful radiations like the X-rays. These are sound waves of high frequencies.
This is widely used by doctors for health checkups. The other name for sonogram is ultrasound.
<span>The correct option is B): meters A and C. In fact, both A and C are ammeters. An ammeter is a device used to measure the current in a branch of a circuit. In order to work properly, an ammeter should be connected in series to a resistor, in order to have the same amount of current that passes through the resistor. In this circuit, we see that devices A and C are both connected in series to a resistor, so they are ammeters. Instead, devices B and D are connected in parallel, so they do not measure the current but the voltage (in fact, they are called voltmeter).</span>
