Use a Graphing Utility to Select the Graph of the Two

Use a graphing utility to select the graph of the two equations in the same viewing window.Use the graphs to determine whether the expressions are equivalent. $\begin{array} { l } y _ { 1 } = 2 \sin x \csc x , \\y _ { 2 } = 2\end{array}$

A)
The expressions are equivalent except sinx = 0, y₁ is undefined.
B)
The expressions are equivalent except when sinx = 0, y₁ is undefined.
C)
The expressions are equivalent except whensinx = 0, y₁ is undefined.
D)
The expressions are equivalent except when sinx = 0, y₁ is undefined.
E)
The expressions are equivalent except when sinx = 0, y₁ is undefined.
