Let a – 2b + c = 1. If f(x)=∣x+ax+2x+1x+bx+3x+2x+cx+4x+3∣f(x)=\left| {\begin{matrix} {x + a} & {x + 2} & {x + 1} \\ {x + b} & {x + 3} & {x + 2} \\ {x + c} & {x + 4} & {x + 3} \\ \end{matrix} } \right|f(x)=​x+ax+bx+c​x+2x+3x+4​x+1x+2x+3​​, then:
  1. A
    ƒ(50) = 1
  2. B
    ƒ(–50) = –1
  3. C
    ƒ(50) = –501
  4. D
    ƒ(–50) = 501
