Task: Answer the multiple choice question.
Question: Which compound has a -2.063% 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 additional words.
Options:
a. O=C(Cc1cccs1)Nc1ccccc1F
b. O=C(OCCOc1ccc(Br)cc1)c1cnccn1
c. CC(C(=O)Nc1ccc(C(=O)O)cc1)N1C(=O)c2ccccc2C1=O
d. COc1ccc(NC(=O)C(C)NS(=O)(=O)c2ccccc2)cc1Cl
e. N#CCC(=O)N/N=C/c1ccc(SCC(=O)Nc2ccccc2)o1
Answer: b. O=C(OCCOc1ccc(Br)cc1)c1cnccn1
