D. `ZnCl_(2)//HCl, FeCl_(3), "Alcoholic HCN"`

Explanation

To solve the question regarding the antifertility drug "Novestrol" and its potential reactions with the given reagents, we need to analyze the structure of Novestrol and the nature of the reagents provided.

### Step-by-Step Solution:

1. **Identify the Structure of Novestrol**:
- Novestrol contains a phenolic group (due to the presence of an -OH group attached to a benzene ring), a cyclohexane ring, and a terminal alkyne group (C≡C).
- The structure can be summarized as having a phenol, an alcohol, and a terminal alkyne.

2. **Evaluate the First Reagent: Br2/H2O**:
- Bromine in the presence of water reacts with phenolic compounds to form tri-bromophenol. This reaction is characteristic of phenols and indicates a positive test.
- Therefore, Novestrol will react positively with Br2/H2O.

3. **Evaluate the Second Reagent: HCl/ZnCl2 (Lucas Reagent)**:
- The Lucas reagent is used to test for the presence of secondary and tertiary alcohols. In this case, the alcohol in Novestrol can behave as a secondary alcohol due to its structure.
- The reaction will lead to the substitution of the -OH group with a -Cl group, indicating a positive test.

4. **Evaluate the Third Reagent: Neutral FeCl3**:
- Ferric chloride (FeCl3) is used to detect phenolic compounds. The presence of phenol in Novestrol will lead to the formation of colored complexes (red, blue, green, or purple).
- Thus, Novestrol will also react positively with FeCl3.

5. **Conclusion**:
- Since all three reagents (Br2/H2O, HCl/ZnCl2, and Neutral FeCl3) give positive tests with Novestrol, the correct option is the one that includes all three reagents.

### Final Answer:
The antifertility drug "Novestrol" can react with all three reagents: Br2/H2O, HCl/ZnCl2, and Neutral FeCl3.
