ARF dependent signalling are regulated by auxin concenteration, given some condition followed;

I) In the absence of auxin

 II) In the presence of auxin

Find the statements that are correctly matched with given certain condition,

a)  AUX/IAA repressor proteins containing interaction domains similar to those found in the ARFs form heterodimers with the ARFs and thus repress transcriptional activation

b)  AUX/IAA repressors are recruited to the TIR1/AFB receptor complex and are tagged with ubiquitin for degradation by the 26S proteasome

c) ARFs form homodimers via conserved interaction domains and recruit chromatin remodelling
