Explanation

**Step-by-Step Solution:**

1. **Understand the Concept of Sublimation:**
- Sublimation is the process in which a solid changes directly into a gas without first becoming a liquid. This occurs when a solid is heated, and it transitions to the gaseous state.

2. **Identify Examples of Sublimation:**
- Common examples of substances that undergo sublimation include naphthalene and camphor. These substances can change from solid to gas when heated without passing through a liquid state.

3. **Analyze the Given Options:**
- The question likely provides multiple choices. We need to evaluate these options to determine which ones involve sublimation.
- For example, if the options include substances like naphthalene and camphor, these are correct as they undergo sublimation.

4. **Eliminate Incorrect Options:**
- Consider options that do not undergo sublimation. For instance, an incense stick or a liquid perfume would not be correct answers, as they do not change from solid to gas directly.

5. **Select the Correct Answer:**
- After analyzing the options, select the one(s) that correctly represent sublimation. In this case, naphthalene and camphor are correct examples.

**Final Answer:**
Sublimation is involved in naphthalene and camphor.
