To determine the correct answer for the question regarding the importance of clinical trials in downstream processing, we need to consider the purpose and nature of clinical trials.

Understanding Clinical Trials

Clinical trials are primarily conducted to assess the safety and efficacy of new drugs or treatments in humans. They are crucial for substances that are intended for use in human medicine.

Analyzing Options

1. Animal feed (A): While processing for animal feed is important, it typically does not require the same clinical trials as drugs for human consumption.

2. Human drugs (B): Clinical trials are essential for human drugs to ensure they are safe and effective for human use. This is the primary context for clinical trials.

3. Pesticides (C): Pesticides may undergo regulatory testing, but they do not require clinical trials in the same way human drugs do.

4. Biofertilisation (D): Similar to pesticides, while biofertilizers need to be tested for efficacy and safety, they do not undergo clinical trials focused on human health.

Conclusion

Based on the analysis, the correct answer is:

B. Human drugs

This option directly relates to the necessity of clinical trials for ensuring the safety and effectiveness of medications intended for human use.
