Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 7.353\% 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 other words.
Options:
a: COc1ccccc1CC(=O)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
b: O=C(Nc1cc(=O)[nH]c2nc(-c3ccccc3)nn12)c1ccccc1Cl
c: O=C(Cc1c(Cl)cccc1Cl)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
d: CCCCNC(=O)Oc1cc(CCl)on1
Answer: a. COc1ccccc1CC(=O)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
