…………. is a hydrophilic molecule.

Options

A. Lipid
B. DNA
C. Palmitic acid
D. None of these

Explanation

To determine which molecule is hydrophilic from the options provided, we can follow these steps:

### Step 1: Understand the term "hydrophilic"
Hydrophilic means "water-loving." Hydrophilic molecules tend to interact well with water and often dissolve in it. They usually have polar or charged groups that can form hydrogen bonds with water.

### Step 2: Analyze the options
The options given are:
- Lipid
- Palmitic acid
- None of these

### Step 3: Evaluate Lipid
Lipids are generally hydrophobic (water-repelling) molecules. They do not dissolve well in water due to their non-polar nature. Therefore, lipids are not hydrophilic.

### Step 4: Evaluate Palmitic Acid
Palmitic acid is a type of fatty acid, which is also hydrophobic. Like other lipids, it does not dissolve well in water. Thus, palmitic acid is not hydrophilic either.

### Step 5: Consider the option "None of these"
Since both lipid and palmitic acid are not hydrophilic, we need to consider if there is another molecule that could be hydrophilic. In the context of the question, if DNA were an option, it would be a hydrophilic molecule due to its charged phosphate backbone.

### Conclusion
Since neither lipid nor palmitic acid is hydrophilic, and if DNA is not listed as an option, then the correct answer would be "None of these."

### Final Answer
None of these.
