Give the Location of the Vertical Asymptote(s) If They Exist $\in$

Give the location of the vertical asymptote(s) if they exist, and state the function's domain in set notation.

A) x = 2; {x | x $\in$ R, x ? 2}
B) x = ; {x | x $\in$ R, x ?
}
C) x = -5, x = -1; {x | x $\in$ R, x ? -5, x ? -1}
D) No vertical asymptote; {x | x $\in$ R}
