Dehydration ..................
Answer: Option C
Explanation:
The statement Calcium builds strong bones are allowed because they are health claims and health claims are allowed on the dietary supplements.
The dietary supplements are the materials or substances that is required when the person's daily requirement is not fulfilled by the food that he eats.
The statement claiming that the supplement helps in building the bones stronger is allowed because this is no therapeutic claim.
Calcium intake in the form of supplements can help make the bones stronger and further it can protect from disease related to bones.
I'm not entirerly sure whether ANY of these statements could be considered untrue.
Socializing up to a certain extent could increase productivity, granted it would be done with work in mind.
B, C, D all are true as these are very commonplace things that can happen at the workplace, while not all are equally probable all of them could happen.
If one really is considered untrue, it most likely would be A.
