Arrange the complex numbers in ascending order: -3 + i, 3 - 2i, -1 + 5i.

  1. -3 + i, -1 + 5i, 3 - 2i

  2. 3 - 2i, -1 + 5i, -3 + i

  3. -1 + 5i, -3 + i, 3 - 2i

  4. -3 + i, 3 - 2i, -1 + 5i

The correct answer is: -3 + i, -1 + 5i, 3 - 2i

To arrange complex numbers in ascending order, we need to order them by their real parts first, and then by their imaginary parts if the real parts are equal. In the given options, 3 - 2i has the largest real part, followed by -3 + i, and finally -1 + 5i. Therefore, option A is the correct answer. Option B and D have the same order of real parts, but in option B, the imaginary parts are in the wrong order. In option C, the order of the real parts is incorrect.
