apo repressor of trp operon is an inactive form of repressor. justify this statement

apo repressor of trp operon is an inactive form of repressor. justify this statement ?

A. Apo-repressor can only bind to the operator site of trp operon when a tryptophan molecule, which is a co-repressor, binds to it.
B. Apo-repressor acts as an inducer if there is a lesser amount of tryptophan present in the surrounding medium and remains inactive when sufficient tryptophan is present.
C. Apo-repressor cannot bind to the operator site of trp operon if a tryptophan molecule, which is a co- repressor, binds to it.

answer : A, an aporepressor always needs to be be bound to a corepressor to be functional
