Task: Answer the multiple choice question.
Question: Which compound has a 13.480\% human ether-à-go-go related gene (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: CC(C)(C)CC(C)(C)NC(=O)c1ccc2snnc2c1
b: O=C1OC(Nc2nccs2)c2ccccc21
c: CN(Cc1nc(-c2ccccn2)no1)S(=O)(=O)c1ccc(Cl)cc1
d: Cn1c(=O)oc2cc(S(=O)(=O)N3CCC(C(=O)NCc4ccccc4)CC3)ccc21
Answer: b. O=C1OC(Nc2nccs2)c2ccccc21
