• D.

Answer: (A)

Verified step by step guidance

1. Understand that a complex number is represented as z = a + bi, where a is the real part and b is the imaginary part.
2. In this problem, the complex number is given as z = 5. This means the real part a = 5 and the imaginary part b = 0.
3. To plot the complex number on the graph, locate the point on the real axis (Re) since the imaginary part is zero.
4. Move horizontally along the real axis to the point where the real part is 5.
5. Mark the point (5, 0) on the graph, which is on the positive side of the real axis.
