Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.016\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(N/N=C/c1cc2c(cc1[N+](=O)[O-])OCO2)c1ccc2c(c1)OCO2
[b] CC(=O)N1C(=O)/C(=N\N(C)c2ccccc2)c2ccccc21
[c] Cc1c(C(=O)O)sc2nc(/C=C/c3ccccc3OC(F)F)[nH]c(=O)c12
Answer: a. O=C(N/N=C/c1cc2c(cc1[N+](=O)[O-])OCO2)c1ccc2c(c1)OCO2
