Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.854\% 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 other words.
Options:
a. COc1cccc(NC(=O)Nc2nnc(Cc3ccc(OC)c(OC)c3)s2)c1
b. CCC(=O)N(Cc1cc2cc(OC)ccc2[nH]c1=O)c1ccc(OC)cc1
c. COc1ccc2nc(Sc3c([N+](=O)[O-])nc(C)n3Cc3ccccc3)[nH]c2c1
d. COc1ccc(S(=O)(=O)N2CCC(C(=O)NCc3ccncc3)CC2)cc1C
Answer: c. COc1ccc2nc(Sc3c([N+](=O)[O-])nc(C)n3Cc3ccccc3)[nH]c2c1
