Task: Answer the multiple-choice question.
Question: Which drug has a 5.399\% 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: CCn1nc(NC(=O)C(C)(C)C)c2cc3cccc(C)c3nc21
b: CN1/C(=C\P(=O)(N(C)C)N(C)C)C(C)(C)c2ccccc21
c: O=C(NC1CC1)c1ccc2c(c1)S(=O)(=O)c1cc(Cl)ccc1C2=O
d: O=C(c1ccc(Cn2c(=S)[nH]c3ccccc3c2=O)cc1)N1CCN(c2ccccn2)CC1
Answer: a. CCn1nc(NC(=O)C(C)(C)C)c2cc3cccc(C)c3nc21
