  • A (0,0)
  • B (1+0i)
  • C (0i - 1)
  • D (1i + 1)
Correct Answer: Option B
Explanation:
The multiplicative identity of a complex number is the number that, when multiplied by any complex number, leaves the original number unchanged. In the set of complex numbers, the multiplicative identity is \(1 + 0i\) (which is simply 1).

So, the correct answer is:

B. (1 + 0i).
