Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.225\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(c1ccccc1)N1CCN(c2ccc([N+](=O)[O-])c(NCc3cccnc3)c2)CC1
b.) CCCCOC(=O)CCc1n[nH]c(=O)[nH]c1=O
c.) O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Br)cc1
Answer: c. O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Br)cc1
