Which option of C, D, or E is the missing reagent to react with the highlighted region #1 to get the product #2?

The image is divided into two sections: reaction pathways on the left and five boxed processes on the right.

### Left Section: Reaction Pathways

1. **First Reaction Box**:
   - Starting compound: Cyclohexene ring with a hydroxyl group (-OH) attached (highlighted in yellow).
   - Reaction conditions: 
     1. BH₃-THF
     2. H₂O₂, NaOH
   - Products: Two potential outcomes depicted:
     - Top product: A heterocyclic compound with a meta-dioxane ring.
     - Bottom product (highlighted in yellow): A cyclohexene with an alcohol group at a new position, indicating hydroboration-oxidation.

### Right Section: Boxed Processes

1. **Unlabeled Box (A)**: 
   - Box contains a vertical arrow without accompanying text.
   
2. **Unlabeled Box (B)**:
   - Similar to Box A, contains a vertical arrow without specific reagents.
   
3. **Box C**:
   - Reagents: HOCH₂CH₂CH₂OH, TsOH, H₂O
   - Vertical arrow suggests a reaction or process following the combination of these reagents.
   
4. **Box D**:
   - Reagents: TsOH, H₂O
   - A vertical arrow again indicates progression to another stage or product.
   
5. **Box E**:
   - Reagents: HgCl₂, H₂SO₄
   - This suggests an acid-catalyzed reaction with mercuric chloride.

In the context of an educational website, the image demonstrates multiple reaction pathways and processes with the use of different reagents and catalysts, illustrating organic chemistry concepts such as hydroboration, oxidation, and acid-catalyzed transformations.

Expert Solution
Step 1: Hemiacetal and acetal

Carbonyl compounds (aldehyde and ketone) react with an alcohol to form hemiacetal in the presence of an acid catalyst by nucleophilic addition reaction mechanism. The hemiacetal reacts with the second molecule of the alcohol to form acetal. These reactions are reversible reactions. An example of acetal formation is as follows:
