✅ Option a — Students of various disciplines
All Options:
- AStudents of various disciplines
- BPersons of different age groups
- CSales of a commodity over a year
- DTemperature recorded during a month.
Detailed Solution & Explanation
Let us analyze the best application of a bar chart:
1. **Bar Chart**: A bar chart is a diagrammatic representation used primarily for qualitative, categorical, or discrete variables where each category can be represented by a distinct bar. The length of the bar is proportional to the value it represents.
2. **Analysis of options**:
- **Students of various disciplines**: Disciplines (such as Science, Commerce, Arts) are distinct qualitative categories. A bar chart is the most appropriate diagram to compare the number of students in these categories.
- **Persons of different age groups**: Age groups are continuous variables grouped into intervals, for which a histogram is more appropriate.
- **Sales of a commodity over a year**: This is time-series data, for which a line diagram (historigram) is usually preferred.
- **Temperature recorded during a month**: This is also time-series data, best represented by a line graph.
Therefore, a bar chart is most suitable for displaying the number of students of various disciplines.
Hence, **Option A** is the correct answer.
