B. formation of amines from amides and `LiAlH_(4)`
C. formation of amines from amides and `Br_(2)`/ NaOH
D. formation of amides from oxime and `H_(2) SO _(4)`

Answer

To solve the question "Which of the following represents Schotten-Baumann reaction?", we will analyze the options provided and identify the correct representation of the Schotten-Baumann reaction.

### Step-by-Step Solution:

1. **Understanding Schotten-Baumann Reaction**:
The Schotten-Baumann reaction is a chemical reaction that involves the formation of amides from acid chlorides and amines. This reaction typically takes place in the presence of a base, such as sodium hydroxide (NaOH), which helps to neutralize the hydrochloric acid (HCl) that is produced during the reaction.

2. **Analyzing the Options**:
We need to evaluate each option to see which one correctly describes the Schotten-Baumann reaction.

- **Option 1**: Formation of amides from amines and acid chloride in the presence of NaOH.
- This option describes the reaction of an acid chloride (RCOCl) with an amine (R-NH2) in the presence of a base (NaOH), leading to the formation of an amide (R-C(=O)-NHR). This is indeed the Schotten-Baumann reaction.

- **Option 2**: Formation of amines from amide and LiAlH4.
- This option describes a reduction reaction where an amide is converted to an amine using lithium aluminum hydride (LiAlH4). This is not the Schotten-Baumann reaction.

- **Option 3**: Formation of amines from amides and Br2 in the presence of NaOH.
- This option describes another reaction that does not relate to the Schotten-Baumann reaction. It involves the conversion of amides to amines, which is not the focus of the Schotten-Baumann reaction.

- **Option 4**: Formation of amides from oxime and H2SO4.
- This option describes a different reaction involving oximes and sulfuric acid, which is not relevant to the Schotten-Baumann reaction.

3. **Conclusion**:
After analyzing all the options, we find that **Option 1** correctly represents the Schotten-Baumann reaction, as it involves the formation of amides from amines and acid chlorides in the presence of NaOH.

### Final Answer:
The correct answer is **Option 1: Formation of amides from amines and acid chloride in the presence of NaOH.**
