• A. (i) and (iii)
• B. (ii) and (iii)
• C. (i) and (ii)
• D. (iii) only

Answer 1

The correct option is C (i) and (ii)

A double bar graph is a graphical display of information using bars at various heights.
We can use a double bar graph to compare two data groups. Therefore, a double bar graph is useful while comparing number of matches won by team in 2018 and 2019 and runs scored in 2018 and 2019 year.
But double bar graphs will not be useful for comparing runs scored in all matches since there is more than two matches.
Therefore, (i) and (ii) are the correct options.
