Answer:
A. Because it pass the vertical line test.
Explanation:
Let us first understand the Vertical Line test. In this test , we draw few random vertical lines on graph and check whether any one or more than one line intersect the graph, no matter once or more. If there exists a line which intersects the graph , we say graph passes the vertical line test.
Hence this graph passes vertical line test because there are many vertical lines which intersect it.
