Q1. Which of the following is the application of computers mostly used in the medical field?
A To create advertisements
B To visualise 3D objects
C To provide distance education
D To provide assistance in surgery Correct
Explanation
In the medical field, computers are widely used to assist in surgery through imaging, monitoring, robotic support and precise planning. Creating advertisements is mainly a commercial or media application, not a medical one. Visualising 3D objects can be useful in design and may sometimes support medical imaging, but the option is broader and less directly tied to the medical field than surgical assistance. Distance education is an educational application. The medical use asked in the question is assistance in surgery.
