Task: Answer the multiple choice question.
Question: Which compound has a 1.790\% human ether-à-go-go related gene (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 additional words.
Options:
a: Fc1ccc(-c2nc(-c3cccs3)[nH]c2-c2ccc(F)cc2)cc1
b: CC1=C(C(=O)OCc2ccccc2)C(c2ccccc2OS(=O)(=O)c2ccc(C)cc2)NC(=O)N1CCCC(=O)O
c: COc1cc(Br)cc(CN2CCN(C=O)CC2)c1O
d: CC(OC(=O)c1ccc(O)cc1)C(=O)Nc1cc(C(F)(F)F)ccc1Cl
Answer: a. Fc1ccc(-c2nc(-c3cccs3)[nH]c2-c2ccc(F)cc2)cc1
