Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.189\% 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: COc1ccc(Br)cc1C(=O)Nc1cccc2ncccc12
b: O=C(CN1CCC(c2nc3ccccc3[nH]2)CC1)NCc1ccc2c(c1)OCO2
c: O=C(/C=C/c1ccc(-c2cccc([N+](=O)[O-])c2)o1)N1CCOCC1
d: CCOc1ccccc1NC(=O)C1=C(C)NC(=O)NC1c1cccc(OC)c1OC
Answer: d. CCOc1ccccc1NC(=O)C1=C(C)NC(=O)NC1c1cccc(OC)c1OC
