Morphology
Although 'plane' (a flat two-dimensional surface) is transparent, the adjective 'complex' here has a specialized mathematical sense ('relating to complex numbers') rather than the common sense 'complicated', so a B1 learner who only knows ordinary word meanings will likely not infer the correct meaning. This is a technical, subject-specific term whose correct interpretation depends on domain knowledge rather than straightforward composition of the common senses.
Etymology
Complex plane comes from a simple picture: a flat plane like a piece of paper where each complex number has a 'real' part and an 'imaginary' part and is shown as a point with a horizontal and a vertical position. So the complex plane means the flat graph where the 'real' values go along the horizontal line and the 'imaginary' values go along the vertical line.
