Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 9.907\% 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 other words.
Options:
a: CN1CCN(C(=O)CCN2C(=O)/C(=C/c3cccc(Br)c3)SC2=S)CC1
b: O=S(=O)(N1CCOCC1)n1c(Cc2ccccc2)nc2ccccc21
c: COc1cccc(C(=O)OCC(=O)Nc2cc(C)c(C)cc2[N+](=O)[O-])c1
d: O=C(NN1CCOCC1)c1ccc(Cl)cc1Cl
Answer: c. COc1cccc(C(=O)OCC(=O)Nc2cc(C)c(C)cc2[N+](=O)[O-])c1
