Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.580% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a C=CCOC(=O)C1=C(C)NC(SCC(=O)Nc2ccc(C)c(Cl)c2)=C(C#N)C1c1ccco1
b COC(=O)C(NS(=O)(=O)c1ccc(NC(C)=O)cc1)C(C)C
c CCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)C1c1ccco1
d CC1Cc2ccccc2N1C(=O)c1ccc(N2CCCCC2)c([N+](=O)[O-])c1
e CC12CCC(C(=O)N3CCc4ccccc43)(CC1=O)C2(C)C
Answer: b. COC(=O)C(NS(=O)(=O)c1ccc(NC(C)=O)cc1)C(C)C
