Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -21.435\% 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: Cc1ccnc(OC(C(=O)O)C(OCc2ccccc2)(c2ccccc2)c2ccc(C(F)(F)F)cc2)n1
b: O=C(Nn1c(-c2ccc(Br)cc2)nc2ccccc2c1=O)c1ccc([N+](=O)[O-])cc1
Answer: b. O=C(Nn1c(-c2ccc(Br)cc2)nc2ccccc2c1=O)c1ccc([N+](=O)[O-])cc1
