Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.158% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1ccc(-c2cc(C(=O)Nc3cnn(C(C)C)c3)no2)cc1
b CCOC(=O)CSc1nc2cc3c(cc2cc1C#N)OCO3
c O=C(/C=C/c1cccs1)N1CCN(c2ccccc2F)CC1
d O=C(CNC(=O)c1ccco1)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
Answer: b. CCOC(=O)CSc1nc2cc3c(cc2cc1C#N)OCO3
