<h3>Hello there!</h3>
Your question asks which person does not use any computer code in their work.
<h3>Answer: D). Computer user support</h3>
The reason why answer choice "D). Computer user support" would be the correct answer is because they don't use any codes when they're at work. A computer user support person would answer phone calls to people that need help in computer related things. This would be also known as a "customer support" for computers. This work does not need any background or current knowledge of coding, due to the fact that they're only answering phone calls and answering any question the customer has. They don't send codes to the person's computer, they tell the person what to do to resolve their problem, and it's nothing involving coding.
