Task: Answer the multiple-choice question.
Query: Which drug has a 5.442\% 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) COc1ccc(NC(=O)CSc2nccn2-c2ccccc2)c(OC)c1
b) CC(C)[C@@H](C(=O)OCC(=O)Nc1ccc2c(c1)OCO2)N1C(=O)c2ccccc2C1=O
c) O=C(Nc1ccc2c(c1)oc1ccccc12)c1ccncc1
d) COc1ccc(Cl)cc1NC(=O)c1cnc2sccn2c1=O
Answer: c. O=C(Nc1ccc2c(c1)oc1ccccc12)c1ccncc1
