One of the following is a random process

Options

A. Variations
B. Adaptations
C. Evolution
D. Mutations

Answer

To solve the question regarding which of the following processes is a random process, we will analyze each option provided: variation, adaptation, evolution, and mutations.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Variation**: This refers to the differences in physical traits of individuals in a population. Variations can arise due to genetic differences, but they are not random as they often result from specific genetic combinations.
- **Adaptation**: This is the process by which a species becomes better suited to its environment. Adaptations are typically the result of natural selection, which is a non-random process.
- **Evolution**: This is the change in the heritable characteristics of biological populations over successive generations. While evolution involves various processes, it is guided by natural selection and is not purely random.
- **Mutations**: These are changes in the DNA sequence of an organism. Mutations can occur randomly and are not directed or pre-planned. They can happen due to various factors, such as environmental influences or errors during DNA replication.

2. **Identifying the Random Process**:
- Among the options, mutations are the only process that occurs randomly. They can happen spontaneously and are not influenced by the organism's needs or environment.

3. **Conclusion**:
- Therefore, the correct answer to the question "One of the following is a random process" is **mutations**.

### Final Answer:
The correct option is **mutations** (Option 4).
