Consider a class named complexNumber. Which code will result in an equivalent object?

complexNumber(float real, float im)
: real_part(real),
im_part(im){}

• A
  complexNumber(float real, float im) {
  this->real = real_part;
  this->im = im_part;
  }
• B
  complexNumber(float real, float im) {
  this->real_part(real);
  this->im_part(im);
  }
• C
  complexNumber(float real, float im) {
  this->real_part = real;
  this->im_part = im;
  }
• D
  complexNumber(float real, float im) {
  this->real_part = ℜ
  this->im_part = &im;
  }
