The answer is A. Shehnai.
A shehnai is a wind instrument that is played in Indian classical music. It is made of wood and has a long, narrow pipe with a flared bell at the end. The shehnai is played by blowing air through a mouthpiece and vibrating the lips. The instrument produces a loud, piercing sound that is often used in religious ceremonies and weddings.
A flute is a woodwind instrument that is played by blowing air across a hole in the instrument. The flute is made of wood or metal and has a long, cylindrical body with a flared bell at the end. The flute is played by holding the instrument horizontally and blowing air across the hole. The instrument produces a high-pitched sound that is often used in classical music.
A trumpet is a brass instrument that is played by blowing air through a mouthpiece and vibrating the lips. The trumpet is made of brass and has a long, cylindrical body with a flared bell at the end. The trumpet is played by holding the instrument vertically and blowing air through the mouthpiece. The instrument produces a loud, high-pitched sound that is often used in jazz and rock music.
A violin is a string instrument that is played by drawing a bow across the strings. The violin is made of wood and has a long, narrow body with a curved back. The violin is played by holding the instrument horizontally and drawing a bow across the strings. The instrument produces a high-pitched sound that is often used in classical music.
The shehnai is different from the other instruments because it is a wind instrument, while the other instruments are string instruments.
