Consider the following fatty acids
1. Linolenic 2.Epimers
3. Aldohexoses 4. Monosaccharides.
which of the above statements are correct ?

Options

A. 1 only
B. 1 and 2
C. 3 and 4
D. 2,3 and 4

Answer

To solve the question regarding the classification of the given terms, we need to analyze each of the four statements provided:

1. **Linolenic**: This is a type of fatty acid, specifically an essential fatty acid that is part of the omega-3 fatty acids group. It is indeed a fatty acid.

2. **Epimers**: Epimers are not fatty acids. They are a type of stereoisomer that differ in configuration at only one specific carbon atom among multiple chiral centers. Therefore, this statement is incorrect.

3. **Aldohexoses**: Aldohexoses are a class of sugars (specifically monosaccharides) that contain an aldehyde group and six carbon atoms. They are not fatty acids, so this statement is also incorrect.

4. **Monosaccharides**: Monosaccharides are the simplest form of carbohydrates and include sugars like glucose and fructose. They are not fatty acids, making this statement incorrect as well.

Now, summarizing the analysis:
- The only correct statement regarding fatty acids is the first one, which refers to linolenic acid.

Thus, the answer to the question is that only the first statement is correct.

### Final Answer:
Only the first statement, "Linolenic," is correct.
