Which are the phases of drug development in biotechnology?

The phases of drug development in biotechnology are accurately represented by the choice that includes discovery, preclinical, trials, and regulatory review. This process begins with the discovery phase, where potential drug candidates are researched and identified, often through various laboratory methods and screening processes to identify biologically active compounds.

After promising candidates are identified, the preclinical phase involves rigorous testing in laboratory and animal studies to assess the safety and biological activity of the compounds. This stage is essential for determining whether a drug is safe enough to progress into human trials.

Once the drug passes preclinical tests, it moves into clinical trials, which are conducted in phases (Phase I, II, and III) to evaluate its safety, effectiveness, dosing, and side effects in humans. After successfully completing these trials, the drug must go through a regulatory review, where organizations like the FDA assess the trial results and the manufacturing processes to ensure compliance with standards before granting approval for marketing.

This structured progression is critical to ensure that any new drug is safe and effective for public use, making choice B the most comprehensive and correct representation of drug development phases in biotechnology.
