Answer 2

The correct answer is A. Bar graph

Explanation:

Bar graphs include two axes one vertical axis (y) and one horizontal axis (x). Besides this, variables in this graph are represented using bars of different height or length according to the variables represented. Additionally, bar graphs are mostly used to show comparisons in a group or changes over time as multiple bars allow readers to understand visually tendencies or changes over months, years, decades, etc. usually by using the X-axis to represent time and Y-axis to represent the other variable.

According to this, in the case presented the most appropriate is a bar graph because this is suitable for showing the growth in a specific population (people aged 65 or more) especially as this evolves over time (1950- 2010) by using bars that represent the differences or changes over the years.
