Final answer:
A will is considered self-proving at the time of probate when it is signed by the testator and witnesses. The correct option is 2.
Step-by-step explanation:
A will is considered self-proving at the time of probate when it is signed by the testator and witnesses. This means that the will has been properly executed and can be admitted to probate without the need to call witnesses to testify about its validity.
The witnesses must sign the will alongside the testator, acknowledging that they witnessed the testator sign the document and that they believe the testator is of sound mind and not under any undue influence.
Hence, Option 2 is correct.
