Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.399\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=c1[nH]c(C(Cl)Cl)nc2sc3c(c12)CCN(Cc1ccccc1)C3
b: CCOC(=O)C1CCN(S(=O)(=O)c2ccc(CN3C(=O)c4cccnc4C3=O)cc2)CC1
c: COc1cc(CN2CCCN(C)CC2)cc([N+](=O)[O-])c1O
Answer: a. O=c1[nH]c(C(Cl)Cl)nc2sc3c(c12)CCN(Cc1ccccc1)C3
