Task: Answer the multiple choice question.
Question: Which compound has a 2.119\% 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: CC(C)CCn1c(NCCc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
b: CC(OC(=O)CCCN=C1NS(=O)(=O)c2ccccc21)C(=O)c1ccccc1
c: CN(Cc1cnn(Cc2ccccc2)c1)C(=O)CN=C1NS(=O)(=O)c2ccccc21
d: Clc1ccc2c(c1)C=Nc1c(ncnc1N1CCOCC1)O2
Answer: b. CC(OC(=O)CCCN=C1NS(=O)(=O)c2ccccc21)C(=O)c1ccccc1
