Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.936\% 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: COc1cccc2cc(C(=O)NCc3ccc(Cl)cc3)c(=O)oc12
b: COc1cc(/C=C2/NC(=O)N(CC(=O)Nc3ccc(C)cc3)C2=O)ccc1Oc1ccc([N+](=O)[O-])cn1
c: Cc1cccc2c1N1C(=O)c3c(C(=O)O)cccc3C1CC2C
d: Cc1ccc(NC(=O)c2ccc(Cl)c(N3C(=O)C=CC3=O)c2)cc1
Answer: a. COc1cccc2cc(C(=O)NCc3ccc(Cl)cc3)c(=O)oc12
