If a chemical process is affected by more than one factors, then its rate will be determined by the factor which is nearest to its minimum value, it is the factor which directly affects the process if its quantity is changed. This is the statement of

Options

A. Hatch and Slack
B. Calvin and Bassham
C. Blackmans law of limiting factor
D. Lindemann's law of minimum

Explanation

To solve the question regarding the statement about the rate of a chemical process being determined by the factor nearest to its minimum value, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Concept**: The question states that when multiple factors affect a chemical process, the rate of that process is determined by the factor that is closest to its minimum value. This implies that if one factor is limiting, it will control the rate of the process.

2. **Identifying the Principle**: This concept is related to the idea that in any physiological or biochemical process, the rate can be limited by the least available resource or factor.

3. **Recognizing the Law**: The principle described is known as Blackman's Law of Limiting Factors. This law states that the rate of a process is determined by the factor that is in the shortest supply when multiple factors are involved.

4. **Conclusion**: Therefore, the statement in the question is a representation of Blackman's Law of Limiting Factors.

### Final Answer:
The statement is a representation of **Blackman's Law of Limiting Factors**.
