Task: Answer the multiple choice question.
Query: Which compound has a -1.780\% 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: Cn1c(=O)c(C(=O)CN2CCc3ccccc32)c(N)n(Cc2ccccc2)c1=O
b: Cc1ccsc1/C=C1/CN(C)Cc2c1nc1ccccc1c2C(=O)O.Cl
c: CCSC1=N/C(=C\c2ccccc2)C(=O)N1c1ccc(OC)cc1
d: CC(=O)c1ccc(NC(=O)C2=CC(c3cccs3)=NS(=O)(=O)N2C)cc1
Answer: a. Cn1c(=O)c(C(=O)CN2CCc3ccccc32)c(N)n(Cc2ccccc2)c1=O
