Correct option is C

The correct answer is (c) Stethoscope
Explanation:
· A Stethoscope is a medical device used to listen to the internal sounds of an animal or human body, a practice known as auscultation.

· The instrument works by amplifying the internal sounds through a chest piece, tubes, and earpieces.
Information Booster:
· The stethoscope was invented in 1816 by French physician René Laennec.
· The modern stethoscope design was pioneered by David Littmann in the 1960s, leading to higher acoustic quality.
· A digital stethoscope can convert acoustic sounds into electronic signals, which can then be amplified, recorded, or filtered.
