Problem statement: Answer the multiple choice question.
Query: Which compound has a 10.655\% 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 Cc1ccccc1-c1nnc(-c2ccc(Cl)cc2)o1
b O=S1(=O)C[C@@H](O)[C@@H](Nc2ccc(Cl)cc2)C1
c COCCCN1CCc2[nH]c(=S)[nH]c(=O)c2C1
d CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)c2oc3ccccc3c2C)cc1
Answer: b. O=S1(=O)C[C@@H](O)[C@@H](Nc2ccc(Cl)cc2)C1
