Directions: Read the following information and answer the given question.

Nearly 66 children of Country K died due to taking a particular syrup. That medicine was imported from a pharmaceutical company based in Country D which sells medicines approved by WHO only. The pharmaceutical exports of Country D have more than doubled over the past decade. The health ministry of Country K has temporarily withdrawn syrups from all pharmacies.

What could be the possible reasons behind the incident?

I. The children have taken an excessive dose of syrup; more than the prescribed limit.

II. The syrup was given to children at home without a doctor’s prescription, either by their parents or on the advice of a pharmacist.

III. Country D exported that syrup with ill intentions to harm the children of Country K due to some political reason.

IV. The health workers showed negligence and didn't analyze the deaths in a timely manner nor took necessary measures.
