Task: Answer the multiple choice question.
Question: Which compound has a 2.190\% 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 additional words.
Options:
a O=C(NCc1ccco1)c1cccc(NC(=O)c2ccco2)c1
b O=C(N/C(=C/c1ccccc1)C(=O)N1CCOCC1)c1ccc([N+](=O)[O-])cc1
c Cc1cc(=O)[nH]c(N/N=C/c2ccc(Br)s2)n1
d O=C(NCc1nc2ccccc2[nH]1)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCCCCO)O1
Answer: a. O=C(NCc1ccco1)c1cccc(NC(=O)c2ccco2)c1
