• D.

Answer: (A)

Verified step by step guidance

1. Identify the complex number given, which is z = 5.
2. Understand that a complex number is of the form z = a + bi, where a is the real part and b is the imaginary part.
3. For the complex number z = 5, the real part a = 5 and the imaginary part b = 0.
4. On the complex plane, the horizontal axis (Re) represents the real part, and the vertical axis (Im) represents the imaginary part.
5. Since the imaginary part is 0, plot the point at (5, 0) on the real axis, which is 5 units to the right of the origin on the horizontal axis.
