Task: Answer the multiple-choice question.
Question: Which drug has a 1.066\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(C(c1ccccc1)c1ccccc1)N1CCN(Cc2ccccn2)CC1
b.) Cn1c(=O)c2c(nc(NCc3ccco3)n2Cc2ccccc2Cl)n(C)c1=O
c.) Cc1cc(C)c2nc(C(F)(F)F)c(C#N)c(N)c2c1
Answer: a. O=C(C(c1ccccc1)c1ccccc1)N1CCN(Cc2ccccn2)CC1
