A student is investigating how temperature affects bacteria growth. The student adds equal amounts of the same kind of bacteria to four separate petri dishes (1, 2, 3, 4). She puts each petri dish in a separate container, each set at a different temperature. She observes and records the total number of bacteria colonies after 36 hours. She summarizes her data in a table.

Question
Which graph ,begin emphasis,best,end emphasis, displays the relationship between temperature and the number of bacterial colonies?
Answer options with 4 options
A.
A pie chart labeled Temperature in degrees Celsius Versus Number of Colonies shows the number of colonies in four sections of the pie chart.
C.
A line graph.Short description, A line graph.,Long description,
A line graph is labeled with Number of Colonies on the x-axis and Temperature in degrees Celsius on the y-axis. The line starts at (9, 30), curves upward sharply, then levels off at (28, 60).
B.
A double bar graph.Short description, A double bar graph.,Long description,
A double bar graph showing Temperature and Number of Colonies. The horizontal axis goes from 1 to 4 and the vertical axis goes from 0 to 70. Temperature starts at 30, and number of colonies starts at 9. Both bars increase steadily.
D.
A line graph.Short description, A line graph.,Long description,
A line graph is labeled with Temperature in degrees Celsius on the x-axis and Number of Colonies on the y-axis. The line starts at (30, 9), curves up gradually, then sharply to (60, 28).
