Task: Answer the multiple choice question.
Question: Which compound has a 17.687% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCn1c(=O)c([N+](=O)[O-])c(NCCc2ccccc2)c2ccccc21
(b) O=C(c1ccccc1F)N1CCN=C1SCc1cccnc1
(c) CC(C)NC(=O)NC(=O)COC(=O)CCOc1ccccc1
(d) CC(C)/C=N/NC(=O)c1cc(Br)ccc1O
Answer: a. CCn1c(=O)c([N+](=O)[O-])c(NCCc2ccccc2)c2ccccc21
