What is a significant disadvantage of using keyboards for data entry?

The choice referring to the potential for repetitive strain injury highlights a significant disadvantage of using keyboards for data entry. This concern is rooted in the nature of keyboard use, which often involves repetitive movements over extended periods. Such repetitive actions can lead to strain on the muscles and tendons in the hands, wrists, and arms, potentially resulting in injuries like carpal tunnel syndrome or tendinitis.

The other options highlight advantages of keyboard use; for instance, increased speed of input and low error rate suggest benefits related to efficiency and accuracy. Flexible input options also indicate that keyboards can accommodate various data entry needs. However, these positive aspects do not negate the physical health risks associated with prolonged keyboard usage, making the risk of repetitive strain injury a noteworthy disadvantage.
