To determine which option is correct, let's examine each choice.
A. A recent illness: Adverse effects are not typically caused by a recent illness. They are usually associated with other factors.
B. A long-standing illness: While a long-standing illness can have its own complications, adverse effects specifically refer to the negative effects resulting from medication or drug use, rather than from the illness itself.
C. The improper use of medication or drugs: This option is generally accurate. Adverse effects commonly occur when medication or drugs are used improperly, such as taking the wrong dosage, not following instructions, or using expired substances.
D. The proper use of medication or drugs: Adverse effects do not occur from the intended and correct usage of medication or drugs. If taken correctly, the risk of adverse effects is minimized.
Therefore, the correct answer is C. The improper use of medication or drugs.
