Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 23.230% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccccc1N1CCN(C2CCCN(C(=O)Cn3cccn3)C2)CC1
b: O=C(NNC(=O)c1cc2ccccc2oc1=O)c1ccccc1[N+](=O)[O-]
c: CC(C)(C)c1csc(NC(=O)CS(=O)(=O)c2ccccc2)n1
d: O=C(COc1ccc2c(-c3ccccc3)cc(=O)oc2c1)N[C@H](Cc1c[nH]c2ccccc12)C(=O)O
Answer: b. O=C(NNC(=O)c1cc2ccccc2oc1=O)c1ccccc1[N+](=O)[O-]
