Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.229\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. Cc1cc(C)c(C#N)c(SCc2ccc(C#N)cc2)n1
b. Cc1ccc(C(C(=O)NC2CCCCC2)N(CCC(C)C)C(=O)CNC(=O)c2ccco2)o1
c. Cc1ccccc1-c1cc(C(=O)NCc2ccc3c(c2)OCO3)n(CC2CC(c3cccnc3)=NO2)n1
d. O=C(Nc1ccc2nc(-c3ccccc3)[nH]c2c1)c1cccs1
Answer: d. O=C(Nc1ccc2nc(-c3ccccc3)[nH]c2c1)c1cccs1
