Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.223\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cn1nc(C(F)(F)F)c(-c2ccc(Br)cc2)c1NC(=O)c1cccnc1
b: O=C(NC1CCCC1)C(c1cc2c(cc1[N+](=O)[O-])OCO2)N1CCCC1
Answer: b. O=C(NC1CCCC1)C(c1cc2c(cc1[N+](=O)[O-])OCO2)N1CCCC1
