Adding adjuvants to a manufactured formulation is desirable when the label of the product specifies or allows for it. Adjuvants are substances that are added to a formulation to enhance its effectiveness. However, adding adjuvants is not always necessary or desirable as it can sometimes interfere with the efficacy of the product. This is why it is important to carefully read the label and instructions before adding any adjuvants. Options B and C are incorrect as they provide extreme answers - it is not always prohibited to add adjuvants, and it is not always necessary or desirable to enhance effectiveness. Option D is incorrect because adjuvants can be added to a formulation even when not mixed with water, as long as it is specified or allowed by the product label. Option A is the only correct answer because it considers the label as the deciding factor for adding adjuvants, ensuring that it is done in a safe and effective manner.
