Task: Answer the multiple-choice question.
Question: Which drug has a 15.214\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a NS(=O)(=O)c1ccc(CCNC(=O)COC(=O)CN2C(=O)C3CCCCC3C2=O)cc1
b O=C(CCc1ccc(O)c(O)c1)N/N=C/c1cc2c(cc1[N+](=O)[O-])OCO2
c C=CCn1c(Cc2ccccc2)nnc1SCc1nc2ccccc2c(=O)[nH]1
Answer: b. O=C(CCc1ccc(O)c(O)c1)N/N=C/c1cc2c(cc1[N+](=O)[O-])OCO2
