Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.002\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) CC(C)OC(=O)CSc1nnc(-c2cccnc2)n1N
b) O=C(O)CC1S/C(=N/N=C2CCCCC2)N(c2ccccc2)C1=O
c) Cc1nn(C(C)C(=O)O)c2ccccc12
d) CN1CCN(C(=O)c2ccccc2N(Cc2ccccc2)S(=O)(=O)c2ccccc2)CC1
e) S=C(Nc1ccc(N2CCOCC2)cc1)Nc1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1
Answer: b. O=C(O)CC1S/C(=N/N=C2CCCCC2)N(c2ccccc2)C1=O
