Select the letter of the type of graph or diagram that would best show

the following information:
the changes in the cost of building a new passenger ship since 1915
a. table e. scale
b. pie chart f. timeline
c. line graph
d. tree diagram

c. line graph

To represent the changes in the cost of building a new passenger ship since 1915, the best type of graph or diagram would be a line graph (option c). A line graph is commonly used to show the trends or changes in data over time. It would allow the cost of building a new passenger ship to be plotted on the y-axis and the years (starting from 1915) on the x-axis. By connecting the dots representing the cost at each year, you can clearly see how the cost has changed over time.
