When did the complete truth come to light according to the statement?

The complete truth came to light after his passing, which indicates that the revelation of information or circumstances was only possible once he was no longer alive. This suggests that certain details may have been hidden or suppressed during his lifetime, perhaps due to the implications they held or the impact they might have had on his reputation or relationships. The timing of the revelation—posthumously—often allows for a clearer context to be established, as any potential biases or emotional responses are removed. This option reflects the understanding that truths can sometimes emerge more freely when individuals are no longer able to be affected by the repercussions of those truths.

In contrast, the other options suggest timings that do not correlate with significant revelations. For example, a serious situation or the timeframe of an investigation may not necessarily lead to a full understanding or exposure of the truth, as there could still be factors preventing complete transparency. Similarly, while he was alive, there would have been potential motivations for withholding certain truths, making the timing after his passing the most indicative of when the truth truly emerged.
