Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -3.315\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCCCCCCCCc1nc2sc3c(c2c(=O)n1NC(=O)c1ccccc1[N+](=O)[O-])CC(C)(C)OC3
b: COCCn1c(-c2ccc(OC)cc2)cnc1N
c: Cn1c(=O)c2c(nc(OCc3ccc4c(c3)OCO4)n2Cc2ccccc2Cl)n(C)c1=O
d: Cc1ccc(OCCCCn2ccnc2C)c(C)c1.O=C(O)C(=O)O
Answer: a. CCCCCCCCCc1nc2sc3c(c2c(=O)n1NC(=O)c1ccccc1[N+](=O)[O-])CC(C)(C)OC3
