V A are vertical lines that correspond to zeroes of the denominator of a rational function.

B) Denominator: 1 - x² = 0

x² = 1, x = 1, or x = - 1

C) x = 0

D) x + x² = 0

x (1 + x) = 0, x = 0 or x = - 1

And finally:

A) 1 + x² ≠ 0, x² ≠ - 1

Answer: function A) does not have a vertical asymptote.
