Which instrument makes sound with strings?

• A. Chorus
• B. Instruments
• C. Strings
• D. Chordophone

Answer: (C)

Sound in string-based instruments comes from the vibrating strings themselves. When a string is plucked, bowed, or struck, it vibrates and these vibrations are amplified by the body of the instrument to produce sound. So, the term that best points to the source of the sound in this context is the strings, since they are the component that actually creates the audible tones. The other options don’t fit as directly: a chorus is a group of singers, not a sound-making element; instruments is too broad a category; chordophone is the technical family name for stringed instruments, but it doesn’t identify what in the instrument makes the sound—the vibrating strings do.
