A: Study of absorption, distribution, binding storage/ biotransformation and excretion of the drug
Answer: A: Study of absorption, distribution, binding storage/ biotransformation and excretion of the drug 
Explanation: Pharmacokinetics (Greek: Kinesis-movement)- What the body does to the drug. This refers to the movement of the drug and alteration of the drug by the body; includes absorption, distribution, binding/localization/storage, biotransformation and excretion of the drug. For example: paracetamol is rapidly and almost completely absorbed orally attaining peak blood levels at 30- 60 min; 25% bound to plasma proteins, widely and almost uniformly distributed in the body (volume of distribution - IL/kg); extensively metabolized in the liver, primarily by glucuronide and sulfate conjugation into inactive metabolites which are excreted in urine; has a plasma half-life (t1/2 )o 2-3 hours and a clearance value of 5 ml/kg/min.
