Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.724\% 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) O=C(CN1C(=O)NC2(CCc3ccccc3C2)C1=O)NCc1ccco1
b) NC(=O)Cn1cnc2c(nnn2-c2ccc(F)cc2)c1=O
c) Cc1nc(NC(=O)c2ccccc2)sc1-c1csc(Nc2ccc(Cl)cc2)n1
d) O=C(CCC(=O)c1ccc(F)cc1)OCc1nnc(-c2ccc([N+](=O)[O-])cc2)o1
Answer: d. O=C(CCC(=O)c1ccc(F)cc1)OCc1nnc(-c2ccc([N+](=O)[O-])cc2)o1
