Answer: (C)

When considering tap targets for touch interfaces, it is important to design with average finger sizes in mind to ensure that users can interact easily and effectively with the interface. The average finger size that designers typically reference for tap targets is around 11 mm in diameter. This measurement is based on usability studies that indicate this size allows for a comfortable and effective interaction. By designing tap targets that are around 11 mm, designers can help ensure that users can easily tap on buttons or other interactive elements without mis-firing or experiencing frustration. A target of this size accommodates the average user’s dexterity and ensures a smoother user experience. Adjusting to a larger or smaller size could lead to accessibility issues or decreased usability for some users.
