Answer: B
Step-by-step explanation: Expressions that include x within the denominator can be solved to find values that cannot be expressed within the domain of the graph. Because there are clear vertical asymptotes at x=1 and x=5, the graph is formed around these areas. The main difference between B and C is that in order for the answer to be C, the graph must pass through y=1, and the graph displayed does not represent that.
