Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.006\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCCCn1c(N)c(N(CC(C)C)C(=O)CN2C(=O)c3ccccc3C2=O)c(=O)[nH]c1=O
b.) COc1ccc(OCc2nnc(NC(=O)Nc3ccccc3F)s2)cc1
c.) COc1cc2c(c(OC)c1OC)-c1c(cc3c(c1OC)OCO3)[C@@H](OC(C)=O)[C@H](C)[C@H](C)C2
Answer: c. COc1cc2c(c(OC)c1OC)-c1c(cc3c(c1OC)OCO3)[C@@H](OC(C)=O)[C@H](C)[C@H](C)C2
