Task: Answer the multiple choice question.
Question: Which drug has a 15.527\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(Nc1ccc(F)cc1)OCCOc1ccc(Br)cc1
b: CCCCNC(=O)OCCSCCS(=O)(=O)c1ccc(Cl)cc1
c: Cc1cc2cc3c(N)[nH]nc3nc2cc1C
Answer: a. O=C(Nc1ccc(F)cc1)OCCOc1ccc(Br)cc1
