Questions: Are all drugs capable of causing side effects?

The answer is the first one (A): Yes, all drugs have inherent side effects.

Explanation for each option:

A. Yes, all drugs have inherent side effects.

• This is correct. All drugs have the potential to cause side effects because they interact with the body in various ways. While the primary goal of a drug is to produce a therapeutic effect, it can also affect other systems or processes in the body, leading to unintended effects.

B. Side effects are only caused by drugs classified as allergelios.

• This is incorrect. The term "allergelios" is not a recognized classification of drugs, and side effects are not limited to any specific class of drugs. All drugs, regardless of their classification, can potentially cause side effects.

C. No, all drugs are designed to not have side effects.

• This is incorrect. While drugs are designed to minimize side effects and maximize therapeutic benefits, it is not possible to create a drug that is completely free of side effects. The complexity of human biology means that any substance that alters physiological processes can potentially cause unintended effects.

In summary, all drugs have the potential to cause side effects, making option A the correct choice.
