Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.173\% 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.) CCOC(=O)Nc1cc(C(=O)OC)ccc1C
b.) O=C(c1ccccc1)c1ccc(COC(=O)c2cnccn2)cc1
c.) Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)NC(C)C1CC2CCC1C2
Answer: b. O=C(c1ccccc1)c1ccc(COC(=O)c2cnccn2)cc1
