Pls help A student conducts an investigation to determine how the force of gravity affects different objects dropped from different heights. The student tests each object one time and announces that all objects experienced gravity the same way. What is wrong with the student’s reasoning?

A. The student failed to create a graph or chart to communicate the results instead of just announcing them.
B. Gravity is unable to be tested with simple experiments, but only in a science lab.
C. People are unable to test the effect of gravity on an object because the force is too strong, so the results were invalid.
D. The student failed to conduct repeated investigations with the same object to test for result reliability.
