General Abdulsalam Abubakar’s regime ended on

Analyze the question: The question asks for the date General Abdulsalam Abubakar's military regime ended. This is a Nigerian history/government fact.

Background:

• General Sani Abacha died suddenly on 8 June 1998.
• General Abdulsalami Abubakar was sworn in as Head of State the next day, 9 June 1998. (Option E, 8 June 1998, is the date Abacha died, so it is a distractor. Option D is the month he took over.)
• Abubakar ran a short transition programme. It included releasing political prisoners, registering political parties, and holding local, state, and national elections in early 1999.
• Olusegun Obasanjo won the presidential election in February 1999.
• Power was handed over to the civilian government, and the Fourth Republic began, on 29 May 1999.

Step-by-step reasoning:

1. His regime began in June 1998, so options D and E refer to the start of his rule, not the end.
2. The handover to a civilian president happened on 29 May 1999, not on 28 or 30 May.
3. So his regime ended on 29 May 1999.

Tip: 29 May is Nigeria's old Democracy Day. It was celebrated until 2019, when the date was changed to 12 June. Remember "29 May 1999 = Abdulsalami out, Obasanjo in." Also remember that Abacha died 8 June 1998 and Abubakar took over right after.
