Task: Answer the multiple-choice question.
Question: Which drug has a 4.679\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccccc1CN=c1c([N+](=O)[O-])nn(-c2ccc3c(c2)OCCO3)n1O
[b] O=C(/C=C/c1cccs1)Nc1nc(-c2ccccc2)cs1
[c] CN1C(=O)Cc2cc(S(=O)(=O)Nc3ccc(Cl)cc3)ccc21
[d] N#Cc1cccc(OCC(=O)NC(=O)NCc2ccccc2)c1
Answer: a. COc1ccccc1CN=c1c([N+](=O)[O-])nn(-c2ccc3c(c2)OCCO3)n1O
