Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.027\% 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 Br.COc1c2c(cc3c1OCO3)CCN(C)C2
b CCOC(=O)c1c(C)n(-c2ccc(OC)cc2)c2ccc(O)c(CN(C)C)c12.Cl
c CCC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(c2ccc(Br)cc2)C1
Answer: c. CCC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(c2ccc(Br)cc2)C1
