What is the meaning of the word incense when it's used in the context of creating a pleasant aroma?

The term “incense” refers to a substance that is specifically used for burning to produce a fragrant aroma. This is often made from a mixture of resins, essential oils, and other aromatic compounds that, when ignited, release pleasing scents into the air. Incense has been employed in various cultures throughout history for purposes such as religious rituals, meditation, or simply to enhance the atmosphere in a space with its fragrance. While the other options present different subjects altogether—like cooking methods, types of trees, or styles of painting—they do not relate to the aromatic qualities associated with incense. The focus is distinctly on the act of burning this substance to create a pleasant aroma, solidifying B as the appropriate choice.
