Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.526\% 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 NC(=O)CC(NC(=O)c1ccccc1)c1ccc(NC2CCC2)c([N+](=O)[O-])c1
b O=C(CCCN1C(=O)/C(=C\c2ccco2)SC1=S)Nc1ccc(O)cc1C(=O)O
c Cc1cc(OCCCCCNCCO)ccc1Cl
d CCOC(=O)c1ccc(Cl)c(NC(=O)c2cccnc2)c1
Answer: d. CCOC(=O)c1ccc(Cl)c(NC(=O)c2cccnc2)c1
