Task: Answer the multiple choice question.
Query: Which drug exhibits a -12.287\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(Nc1ccccn1)C12CC3CC(CC(C3)C1)C2
b) Cc1cc(C)cc(NC(=O)CSc2nc3ccncc3[nH]2)c1
c) Clc1ccc(OCCN2CCCCC2)c(Cl)c1.O=C(O)C(=O)O
Answer: a. O=C(Nc1ccccn1)C12CC3CC(CC(C3)C1)C2
