Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.396\% 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. CCOC(=O)C(C)Sc1nc2c([nH]c3ccccc32)c(=O)n1C
b. CC1CCc2c(sc(NC(=O)C3CCCO3)c2C#N)C1
c. CCCCc1ccc(NC(=S)Nc2ccc(Cl)c(S(=O)(=O)N(C)C)c2)cc1
d. Cc1c(C(=O)N(C)CCC#N)oc2ccc(S(=O)(=O)N3CC(C)CC(C)C3)cc12
Answer: d. Cc1c(C(=O)N(C)CCC#N)oc2ccc(S(=O)(=O)N3CC(C)CC(C)C3)cc12
