Which option is an example of technology increasing service reach?

Correct answer: Online classes being available for distant students

The direct answer is A: online classes being available for distant students. Service reach means the number or geographical area of people who can receive a service. Technology, especially the internet and video communication, allows a teacher to teach students who are far away. The reasoning is: online platform removes much of the distance barrier, distant students connect digitally, and the same educational service reaches more people. Option A is correct. Option B, accepting only cash, restricts payment choices and does not extend a service to new locations or users. Option C, using an old lock, concerns security and gives no evidence that a service reaches more customers. Option D, writing product lists by hand, is a manual record-keeping method and does not expand access. The key distinction is between improving an internal activity and increasing access. Online classes directly connect providers and users across distance. Remember: in a question about technology increasing reach, look for internet-based delivery such as online classes, telemedicine, or digital banking.
