Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.238\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CCn1c(=N)n(CC(O)c2ccco2)c2ccccc21.Cl
b) O=C(N/N=C/c1ccc(Cl)s1)c1ccccc1[N+](=O)[O-]
c) Cn1ccc(-c2ccccc2)n1
d) O=C1c2ccccc2OC2(C=Cc3ccccc3O2)N1Cc1ccccc1
Answer: c. Cn1ccc(-c2ccccc2)n1
