Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.964\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CSc1ncn[nH]1)N/N=C/c1ccc(C(F)(F)F)cc1
b O=C(Nn1c(-c2ccncc2)nc2ccccc2c1=O)c1ccc([N+](=O)[O-])cc1Cl
c Cc1cc(NN)nc(NS(=O)(=O)c2ccc(Cl)cc2)n1
d CN(C)CCNC(=O)C(=O)c1c(-c2ccccc2)cc2ccccn12
Answer: b. O=C(Nn1c(-c2ccncc2)nc2ccccc2c1=O)c1ccc([N+](=O)[O-])cc1Cl
