Which among the following is the allosteric activator of acetyl CoA carboxylase?

Acetyl-CoA carboxylase is an allosteric enzyme and is activated by citrate, which increases in concentration in the well-fed state and is an indicator of a plentiful supply of acetyl-CoA. Citrate promotes the conversion of the enzyme from an inactive dimer to an active polymeric form, with a molecular mass of several million. Ref: Botham K.M., Mayes P.A. (2011). Chapter 23.
