Problem statement: Answer the multiple choice question.
Query: Which compound has a 13.300\% 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 other words.
Options:
a: O=C(c1ccccc1F)N1CCCc2ccccc21
b: CC(C)(C)c1ccc(/C=C2\SC(=O)N=C2N)cc1
c: c1cncc(-c2nc(-c3cccs3)cs2)c1
d: Cn1c(=O)c2cc(NCc3ccccc3)nnc2n(C)c1=O
Answer: d. Cn1c(=O)c2cc(NCc3ccccc3)nnc2n(C)c1=O
