Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.608\% 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: Cc1cccc(NP(=O)(Oc2ccccc2)Oc2ccccc2)c1C
b: CC(C(=O)N1CCOCC1)c1ccc([N+](=O)[O-])cc1
c: Cc1cc(C)nc(N2CCC(C(=O)NCc3ccccc3)CC2)n1
d: COCCN1C(=O)N(C)[C@@H](c2ccccc2)C(C(C)=O)=C1C
Answer: b. CC(C(=O)N1CCOCC1)c1ccc([N+](=O)[O-])cc1
