B. Nucleic acids serve as genetic material .
C. Proteins , nucleic acids and polysaccharides are the only three of macromolecules found in the living system.
D. Collagen is the most abundant protein in the whole of the biosphere and RuBisCo is the most abundant protein in the as animal world .

Answer

To solve the question of selecting the wrong statement from the given options, we will analyze each statement one by one.

### Step 1: Analyze the first statement
- **Statement**: "Ribozymes are nucleic acids with catalytic power."
- **Analysis**: This statement is correct. Ribozymes are indeed RNA molecules that have the ability to catalyze specific biochemical reactions, such as RNA splicing.

**Hint**: Remember that ribozymes are a type of RNA that can act as enzymes.

### Step 2: Analyze the second statement
- **Statement**: "Nucleic acid serves as the genetic material."
- **Analysis**: This statement is also correct. Both DNA and RNA are types of nucleic acids that serve as genetic material in living organisms.

**Hint**: Consider the roles of DNA and RNA in heredity and genetic information.

### Step 3: Analyze the third statement
- **Statement**: "Proteins, Nucleic Acid, and Polysaccharides are the only three macromolecules found in the living system."
- **Analysis**: This statement is correct. Proteins, nucleic acids (DNA and RNA), and polysaccharides (carbohydrates) are indeed the primary macromolecules found in living organisms.

**Hint**: Recall the four major classes of biological macromolecules and their functions.

### Step 4: Analyze the fourth statement
- **Statement**: "Collagen is the most abundant protein in the whole of the biosphere and Rubisco is the most abundant protein in the animal world."
- **Analysis**: This statement is incorrect. Collagen is the most abundant protein in the animal world, while Rubisco (Ribulose bisphosphate carboxylase/oxygenase) is the most abundant protein in the biosphere, particularly in plants.

**Hint**: Think about the roles of collagen and Rubisco in animals and plants, respectively.

### Conclusion
After analyzing all the statements, we find that the fourth statement is the wrong one. Therefore, the correct answer is:

**Answer**: Option 4
