Fill in the missing reactant, reagent, or product for the following reaction.

### Organic Chemistry Reaction Pathway

**Problem (b):**

**Hint:** Single molecule starting material!

**Reaction Details:**

- **Starting Material:** Not specified in the image.
- **Reagent/Catalyst:** H₂SO₄ (sulfuric acid), acts as a catalyst.
- **Condition:** Heat is applied.
- **Product:** The product is a six-membered cyclic ether, specifically tetrahydropyran.

**Diagram Explanation:**

- A reaction arrow points from the starting material (not shown) to the product, tetrahydropyran. 
- Above the arrow, the catalyst “H₂SO₄ (cat)” is listed, indicating that sulfuric acid is used in catalytic amounts to facilitate the reaction.
- Below the arrow, the condition “Heat” suggests that the reaction requires elevated temperatures to proceed. 

This setup suggests an intramolecular ring closure to form a cyclic ether from a linear precursor. The presence of sulfuric acid as a catalyst indicates an acid-catalyzed dehydration or substitution process.
