Gibberellin is an important plant hormone that regulates several aspects of plant growth and development. Some statements are given below in relation to  signalling pathways:

a) The binding of gibberellin (GA) to its receptor leads to the degradation of the DELLA repressor by the 26S proteasome

b) Gibberellin binds to the GID1 receptor and induces a conformational change in the N-terminal domain of the receptor, allowing the receptor to interact with the TVHYNP and DELLA domains of the DELLA repressor

c) The formation of the GID1-repressor complex promotes the interaction between the repressor and the E3 ubiquitin ligase SCF^TIR1 complex, leading to the ubiquitination and degradation

d) The gibberellin receptor GIBBERELLIN INSENSITIVE DWARF 1 (GID1) also itself function as an F-box protein

Which one of the following is the incorrect statements about GA  signalling pathway;
