Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.748\% 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) c1cncc(C(c2nnnn2C2CCCCC2)N2CCCCC2)c1
(b) O=C(O)C(=O)O.O=[N+]([O-])c1cc2c(cc1CN1CCN(C/C=C/c3ccccc3)CC1)OCO2
(c) Nn1cnc2c([nH]c3ccccc32)c1=O
Answer: c. Nn1cnc2c([nH]c3ccccc32)c1=O
