  • ✓
    Constant
  • B
    Modulus
  • C
    Identity
  • D
    Signum function
✓

Answer

Correct option: A.
Constant
$\{(-1, 1), (1, 1), (-2, 2), (2, 2), (-3, 3), (3, 3), ……\}.$ This function involves relation $\{(x, y), y = |x|\}$ which is involved in modulus function.
So, above function is modulus function.
