Task: Answer the MCQ question.
Query: Which compound exhibits a -19.491% 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 CC(=O)C1=C(c2cccc([N+](=O)[O-])c2)N(C(C)=O)n2c(C)nnc2S1
b Cl.Oc1ccc(C2=CSC3=NCCN23)cc1O
c O=C(CN1CCN(c2ccccc2)CC1)Nc1ccncc1
d CCOCCOC(=O)C1=C(C)N(C)C(=O)NC1c1ccccc1Cl
Answer: a. CC(=O)C1=C(c2cccc([N+](=O)[O-])c2)N(C(C)=O)n2c(C)nnc2S1
