The correct answer is D. Shehnai.
A shehnai is a double-reed wind instrument that is played in Indian classical music. It is traditionally used in weddings and other auspicious occasions. The shehnai is made of wood and has a long, cylindrical body with a flared bell at the end. The two reeds are made of cane and are attached to a mouthpiece. The shehnai is played by blowing air through the mouthpiece and vibrating the reeds. The instrument produces a loud, piercing sound that is often used to create a sense of excitement and festivity.
