Final answer:
A synthesizer is an electronic instrument capable of creating a wide variety of sounds, from imitations of traditional instruments to unique electronic textures. Option A.
Step-by-step explanation:
An electronic instrument that can make a wide variety of sounds is a synthesizer. Unlike organs, acoustic pianos, and djembe drums, synthesizers can generate and manipulate a vast array of sounds which can mimic traditional instruments or create entirely novel electronic sounds. They function by combining and modulating waveforms from oscillators, which are then shaped through filters, envelopes, and effects to create different textures and timbres.
An electronic instrument that can make a wide variety of sounds is a synthesizer. A synthesizer is capable of producing a wide range of sounds by manipulating electrical signals. It can imitate various instruments and create unique, synthesized sounds.
