Easy -1.2 This is a straightforward recognition question requiring students to identify a circle's equation from its Argand diagram by reading off the center and radius. While it's a Further Maths topic (complex numbers loci), it's a 1-mark multiple choice question testing only basic recall of the form |z - z₀| = r, making it easier than average overall.
The diagram below shows a locus on an Argand diagram.

Which of the equations below represents the locus shown above?
Circle your answer.

\(|z - 2 + 3\mathrm{i}| = 2 \quad |z + 2 - 3\mathrm{i}| = 2 \quad |z - 2 + 3\mathrm{i}| = 4 \quad |z + 2 - 3\mathrm{i}| = 4\)
