Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.507% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(c1cc(-c2ccc(Br)cc2)nc2ccccc12)N1CCN(c2ccccc2O)CC1
(b) C[C@H](NC(N)=O)C(=O)OCC(=O)NCc1cccs1
(c) O=C(CNCC1CCCO1)Nc1ccc([N+](=O)[O-])cc1C(=O)Nc1ccccc1F
(d) COc1ccc(Oc2nc3ccccc3n(C)c2=O)cc1
(e) O=C(CNC(=O)c1ccc(Oc2ccccc2)cc1)OC1CCCCC1=O
Answer: a. O=C(c1cc(-c2ccc(Br)cc2)nc2ccccc12)N1CCN(c2ccccc2O)CC1
