Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.153\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(C(=O)Oc2cc(N)n(S(=O)(=O)c3ccc(C)cc3)n2)cc1
b COc1ccccc1N1C(=O)S/C(=C\c2cccs2)C1=O
c O=C(Nc1ccc(Cl)cc1N1CCOCC1)C1CCCCC1
d C=CCOC(=O)COc1ccc2c(C)c(C)c(=O)oc2c1C
Answer: b. COc1ccccc1N1C(=O)S/C(=C\c2cccs2)C1=O
