INEC had given the APC December 1 deadline to submit a replacement for Audu, who died from a heart attack after the state's governorship election was declared inconclusive.
The APC forwarded Bello's name to the Commission a few hours to deadline, after hours of deliberations.
There is, however, been confusion in the state as to who the right candidate for Audu's replacement would be.
As Bello becomes APC's flagbearer, he will face major opponent, the incumbent Governor of Kogi State, Idris Wada of the Peoples Democratic Party (PDP) in the supplementary election scheduled to hold on Saturday, December 5.
"They have sent the name of their replacement candidate, the second runner-up in their primaries, that is Yahaya Bello, to the commission.
"The commission is committed to conduct the two elections,that is why in respect of kogi, in spite of what happened, we came out with public notice which invites the APC to submit its replacement candidate for the election",INEC's Deputy Director, Publicity, Nick Dazang said.
INEC had ruled last week's governorship election in the state inconclusive following reports to irregularities in 91 polling units.
