Choose the correct reagents for the following synthesis:

1. Correct reagent(s) for Step I
   - [ Select ]

2. Correct reagent(s) for Step II
   - [ Select ]

3. Correct reagent(s) for Step III
   - [ Select ]

4. Correct reagent(s) for Step IV
   - [ Select ]

5. Correct reagent(s) for Step V
   - [ Select ]

Options for reagent selection:
- A. 1. CH3CH2OH/MgBr 2. H3O+
- B. CH3CH2MgBr/THF
- C. 1. CH3CH2OMgBr/THF 2. H3O+

### Diagram Explanation:

Below the selection options, there is a series of chemical structures that represent different reaction steps labeled I through V.

- **Step I to Step II**: The structure shows the transformation of a compound containing a hydroxyl group (OH) and a carbonyl group into another compound, suggesting a reaction involving the carbonyl functionality.

- **Step II to Step III**: This step indicates a cyclization process where a new ring is formed, converting one functional group into a cyclic ether.

- **Step III to Step IV**: A Grignard reagent (OMgBr) appears here, implying the use of an organometallic reagent in the reaction.

- **Step IV to Step V**: The structure suggests the transfer of a functional group to form a new nitrogen-containing heterocycle, completing the synthesis.

Each step likely involves specific reagents that facilitate the transformations described. These reagents are chosen via a dropdown selection for each step.
