Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.658\% 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. Cc1ccc(C(=O)N(C)CCOc2ccccc2)cc1S(=O)(=O)N1CCOCC1
b. CCN1CCN(CC(=O)Nc2cc(C)c(C)cc2[N+](=O)[O-])CC1
c. O=[N+]([O-])c1cc(C(F)(F)F)cc([N+](=O)[O-])c1NN=C1CCCCC1
d. CCN(CC(=O)Nc1c(F)cccc1F)C(=O)c1ccc(COc2ccccc2)o1
Answer: c. O=[N+]([O-])c1cc(C(F)(F)F)cc([N+](=O)[O-])c1NN=C1CCCCC1
