Task: Answer the multiple choice question.
Question: Which compound has a 3.587\% 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(N/N=C/c1ccc(O)c(O)c1)c1cccc(S(=O)(=O)N2CCCC2)c1
b O=C(Cc1nnc(NC(=O)Nc2ccc(F)cc2)s1)NCc1ccccc1
c NC(=O)Cn1nc([N+](=O)[O-])nc1Oc1ccc(Br)cc1
d CCOc1cc(S(=O)(=O)n2ccnc2)ccc1Br
Answer: c. NC(=O)Cn1nc([N+](=O)[O-])nc1Oc1ccc(Br)cc1
