Based on the novel The Lekki Headmaster, what disrupted the Ignatius family's relocation plans?

The Ignatius family's relocation plans were disrupted when a DNA test revealed that Mr. Ignatius was not Favour's biological father. Favour is their fifteen-year-old daughter, and this discovery shattered the family. The revelation led to a severe domestic crisis in which Mr. Ignatius (also referred to as Mr. Ibe in the narrative) told Mrs. Ignatius and Favour to leave the house.

This plot development is one of the novel's most dramatic moments. The family had been preparing for emigration, with Mrs. Ignatius even learning new vocational skills. However, the DNA result brought everything to a halt, as the personal turmoil it caused made relocation impossible. The incident illustrates how unforeseen personal crises can derail even the most carefully laid plans.

The other options do not reflect what happened in the novel. Mr. Ignatius did not lose his job, Mrs. Ignatius did not simply change her mind, and their visa application was not denied. The disruption was entirely personal in nature, arising from the DNA test result.
