Correct: A — observation only, since the prognosis is good. A tumour-volume-to-fetal-weight ratio of 0.08 at 24 weeks is below the 0.12 threshold that predicts hydrops and poor outcome, so serial surveillance is all that is needed. Termination, radiofrequency ablation and open fetal resection (options B, C and D) are reserved for high-ratio tumours with evolving hydrops.
