Problem statement: Answer the multiple choice question.
Query: Which compound has a 4.115\% 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 additional words.
Options:
a: O=C(NNC(=O)c1cc2ccccc2cc1O)Nc1ccccc1F
b: CSCC[C@@H](C(=O)NCCCCCCCCCCC(=O)N1CCNCC1)n1cc(CCO)nn1
c: O=C1C=C(c2cc3ccccc3s2)C[C@@H](c2ccc3c(c2)OCO3)C1
d: CN(C)C(C/C=N/OCc1ccccc1Cl)=C(C#N)C#N
Answer: a. O=C(NNC(=O)c1cc2ccccc2cc1O)Nc1ccccc1F
