Options

A.
B. b. `Me--=-Me`
C.
D.

Explanation

To solve the question regarding hydroboration oxidation and acid hydration yielding the same product in the case of symmetrical alkynes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hydroboration and Oxidation**:
- Hydroboration involves the addition of boron (BH3) to the alkyne, followed by oxidation with hydrogen peroxide (H2O2) in the presence of a base (OH-). This process leads to the formation of an alcohol.

2. **Understanding Acid Hydration**:
- Acid hydration involves the addition of water (H2O) across the triple bond of the alkyne in the presence of an acid (like H2SO4) and a catalyst (like Hg2+). This reaction also leads to the formation of an alcohol.

3. **Identifying Symmetrical Alkynes**:
- Symmetrical alkynes are those where the substituents on either side of the triple bond are the same. For example, in the alkyne R-C≡C-R, both R groups are identical.

4. **Analyzing the Products**:
- When the alkyne is symmetrical, both hydroboration oxidation and acid hydration will yield the same product because the addition occurs in a way that does not create different isomers.
- For example, if we take 2-butyne (CH3-C≡C-CH3), both reactions will yield the same alcohol (butan-2-ol).

5. **Conclusion**:
- Therefore, hydroboration oxidation and acid hydration will yield the same product in the case of symmetrical alkynes.

### Final Answer:
Hydroboration oxidation and acid hydration will yield the same product in the case of symmetrical alkynes.
