The correct answer is A. 16.
Tally is a free and open-source statistical software package for Windows, macOS, and Linux. It is designed to be easy to use and can be used for a variety of statistical tasks, including data entry, data analysis, and data visualization.
Tally has a predefined number of groups, which can be used to organize data. The number of groups is 16, but it can be changed by the user.
The following are the four options in the question:
- A. 16
- B. 28
- C. 128
- D. 228
Option A is the correct answer. Option B is incorrect because the predefined number of groups is 16, not 28. Option C is incorrect because the predefined number of groups is 16, not 128. Option D is incorrect because the predefined number of groups is 16, not 228.
I hope this helps!
