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.
Doing so would not only increase your productivity potential / but also increase your productivity STANDARDS for certain jobs (e.g. data entry; secretarial work), which is a direct skill that is valuable to employers. Furthermore, if you work in a a secretarial job, this would allow you to accomplish tasks such as "touch typing" a lot faster (without sacrificing quality) — allowing you more time to accomplish other tasks, making you more efficient and even promotable in terms of pay raise and in terms of promotable to other positions with higher earnings — and even teach new staff members.
