In the figure shown, X₂X₁X₀ will be 1's complement of A₂A₁A₀ if
$${\overline {\text{A}} _0} = {\overline {\text{A}} _1} = {\overline {\text{A}} _2}$$

A. Y = 0

B. Y = 1

C. $${\text{Y}} = {\overline {\text{A}} _0} = {\overline {\text{A}} _1} = {\overline {\text{A}} _2}$$

D. $${\text{Y}} = {{\text{A}}_0} = {{\text{A}}_1} = {{\text{A}}_2}$$

Answer: Option B
