A). Yes, because it passes the vertical line test.
Step-by-step explanation:
The vertical line test is defined as the method that is employed to ascertain whether a curve displayed in the graph follows a function or not.
As per this test, a function must possess only one output 'y' in return for every distinct input, x.
Thus, the given graph represents a function because it qualifies the above vertical line test as all the given vertical lines are intersecting the curve atleast once. Hence, option A is the correct answer.
