The correct option is A continuous graph
The given graph is a continuous graph because it has a value of y for every single value of x, and each point is immediately adjacent to the point on either side of it, resulting in an uninterrupted graph line.
While Discrete graphs show values along a number line at precise point. These graphs do not include any values that are not whole numbers.
Hence,the given graph is a continuous graph.
Option (a) is correct.
