Task: Answer the multiple choice question.
Query: Which compound has a 1.708\% 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 additional words.
Options:
a: O=C(O)c1ccc(NCCc2ccc(Cl)cc2)c([N+](=O)[O-])c1
b: COc1ccc(-c2csc3nc(-c4ccc(C)cc4)oc(=O)c23)cc1OC
c: CCn1c(SCC(=O)N(C)c2c(N)n(Cc3ccccc3)c(=O)[nH]c2=O)nc2ccccc21
d: Cc1nnc(-c2cnn(C)c2N)n1Cc1ccccc1
Answer: a. O=C(O)c1ccc(NCCc2ccc(Cl)cc2)c([N+](=O)[O-])c1
