Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.057% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1nn(Cc2cccc(C(=O)O)c2)c(C)c1[N+](=O)[O-]
b O=[N+]([O-])c1ccc(OCCCOc2cccc3cccnc23)cc1
c CC(C)CNC(=O)c1ccc2c(c1)C(=O)N(Cc1ccco1)C2=O
d CCc1ccc(-c2nc3ccc(Br)cc3c(C(=O)O)c2C)s1
Answer: d. CCc1ccc(-c2nc3ccc(Br)cc3c(C(=O)O)c2C)s1
