Task: Answer the multiple choice question.
Question: Which compound has a 20.653% 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(c1ccccc1)n1ccc(-c2cccs2)n1
b: Cc1ccc(C(=O)c2c[nH]c(C(=O)NCCCN3CCOCC3)c2)cc1
c: Cc1ccc2nc(NC(=O)CSc3nc(=O)n(CCCN(C)C)c4c3CCC4)sc2c1
d: CCC(C)NS(=O)(=O)c1ccc(S(=O)(=O)Nc2cc3c(cc2C(C)=O)OCO3)cc1
e: COc1ccc(-n2c(NC(=O)c3ccco3)c(C#N)c3nc4ccccc4nc32)cc1
Answer: a. O=C(c1ccccc1)n1ccc(-c2cccs2)n1
