Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.309\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOCCCNC(=O)Cn1cnc2c(cnn2-c2ccc(OC)cc2)c1=O
b: COc1ccc(C(CC(=O)NCCCN2CCOCC2)NS(=O)(=O)c2ccc(C)cc2)cc1
c: COc1ccccc1-c1csc(Cc2nnc3n2CCCCC3)n1
d: O=[N+]([O-])c1ccc(N/N=C2/CCCCC2c2ccccn2)c([N+](=O)[O-])c1
Answer: b. COc1ccc(C(CC(=O)NCCCN2CCOCC2)NS(=O)(=O)c2ccc(C)cc2)cc1
