Task: Answer the MCQ question.
Query: Which compound has a 4.321\% 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) Cc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccc(Br)cc1)=N2
b) Cc1cccc(OCC(=O)N/N=C/c2ccc(N(C)C)cc2)c1
c) CCOc1ccc(C(=O)COC(=O)CNC(=O)C2CCCCC2)cc1
d) NN1C(=O)/C(=C\c2ccco2)SC1=S
Answer: a. Cc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccc(Br)cc1)=N2
