Answer:
A
Step-by-step explanation:
First, the definition of a floor function is that you round down, whereas for a ceiling function, you round up no matter what.
So, since C and D have the definitions totally wrong inherently, we can eliminate those.
Looking at the graph, we see that all the segments have their leftmost circle filled in. This indicates that the smaller number is counted. So, it's a floor function graph.
Thus, the answer is A.
