Task: Answer the multiple-choice question.
Question: Which drug has a 17.860\% 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(NCc1ccc2c(c1)OCO2)Nc1ccc([N+](=O)[O-])cc1
b.) O=C(NCC1CCCO1)c1cc(-c2ccc(F)cc2)no1
c.) Cc1cccc(-n2c(=S)[nH]c3c(oc4ccccc43)c2=O)c1
Answer: a. O=C(NCc1ccc2c(c1)OCO2)Nc1ccc([N+](=O)[O-])cc1
