What does the term "dulcet" mean?

The term "dulcet" specifically refers to sounds that are pleasing and soothing to the ear. It is often used to describe melodies, tones, or voices that are sweet and gentle. When something is described as dulcet, it evokes a sense of tranquility and enjoyment in the listener, making it a fitting term for music or spoken words that are harmonious and delightful. This understanding aligns perfectly with the definition implied by the correct answer.

The other options represent entirely different concepts: "natural ability" relates to an inherent skill or talent, "arrogant attitude" denotes a sense of superiority over others, and "political system" refers to the structure of governance or the means by which a society organizes its political activities. None of these capture the essence of "dulcet," which is grounded in auditory experience and appreciation.
