Task: Answer the multiple choice question.
Question: Which compound has a -1.763\% 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: Cc1[nH]nc2c1C(c1ccc(F)cc1)C(C#N)=C(N)O2
b: O=C(CCCN1C(=O)c2ccccc2C1=O)OC1CSCC1NC(=O)c1ccccc1
c: CSC(=Nc1ccccc1)C(C#N)c1nc2ccccc2[nH]1
d: COc1cccc(-n2nnnc2SCC(=O)Nc2ccccc2OC)c1
Answer: a. Cc1[nH]nc2c1C(c1ccc(F)cc1)C(C#N)=C(N)O2
