Task: Answer the multiple choice question.
Question: Which compound has a 9.969\% 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) CN1CCc2nc(SCC(=O)Nc3cccc(F)c3)c(C#N)c(-c3cccs3)c2C1
b) COc1cccc(NC(=O)C(NC2CCCC2)c2ccccc2)c1
c) O=C(COC(=O)c1cncc(Br)c1)NCC1CCCO1
d) O=C(CCc1nnc(CCCCc2ccccc2)o1)NCCN1CCOC1=O
Answer: c. O=C(COC(=O)c1cncc(Br)c1)NCC1CCCO1
