Task: Answer the multiple choice question.
Question: Which compound has a 8.209\% 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) CC(=O)NCCOc1cccc(OCCNC(C)=O)c1
b) N#C/C(=C/c1ccccc1[N+](=O)[O-])C(=O)NCc1ccco1
c) O=c1[nH]c(=O)n([C@H]2C[C@H](O)[C@@H](CO)O2)cc1Br
d) CCC(C)(C)n1nnnc1C(c1ccccc1F)N1CCC(C(N)=O)CC1
Answer: c. O=c1[nH]c(=O)n([C@H]2C[C@H](O)[C@@H](CO)O2)cc1Br
