I would say B because Carpal tunnel syndrome is caused by repetitive flexing and extending of tendons (it gets worse if it's for a long time) pressure on the median nerve can cause pain numbness and weakness in the hand and wrist. So this is the best answer as it shows there is a poor working environment it would be better if there was something as simple as a mouse pad that the wrist could lay on while using the mouse for example or using padding on the desk could improve the working environment and prevent this. 
 
        
             
        
        
        
Answer:
Based on the discussions during iteration planning, team members agree on what each would work on.
Explanation:
Iteration can be defined as the way in which a process is been repeated in order to generate a possibly outcomes and this occur in a situation where the sequence will approach some end point in which each repetition of the process will be a single iteration while the outcome of each iteration will then be the starting point of the next iteration.
Therefore the team know what to work upon during the iteration Base on the discussions during iteration planning in which the team members agree on what each of them would work on. 
During the iteration planning, the team collectively make a decision on how much of the backlog actually they will commit to the iteration in which the committed backlog then is taken to the delivery during the next iteration which is why the goals or objectives of the iteration get determined on the basis of the work committed.
