Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.562% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCn1nnnc1SCC(=O)NNC(=O)C1CCCCC1
b) O=[N+]([O-])c1cc(-c2ccc(/C=N/n3cnnc3)o2)ccc1Cl
c) COC(=O)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)[C@@]2(C)NC(=O)c2ccccc2)[C@H](c2ccccc2)n2c(=O)n(-c4ccccc4)c(=O)n2[C@@H]3C1
Answer: c. COC(=O)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)[C@@]2(C)NC(=O)c2ccccc2)[C@H](c2ccccc2)n2c(=O)n(-c4ccccc4)c(=O)n2[C@@H]3C1
