Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.025\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(C1CCN(S(=O)(=O)c2cccc3cccnc23)CC1)N1CC=C(c2ccccc2)CC1
(b) C[C@@H](C(=O)Nc1ccc2ccccc2c1)[C@H]1C[C@]1(C)[C@H](NC(=O)c1cnccn1)c1ccccc1
(c) O=C1/C(=C/c2ccco2)Cc2ccccc21
(d) Cc1ccc(N(C(=O)C2CCCO2)C2C=CS(=O)(=O)C2)cc1Cl
(e) COc1ccc(S(=O)(=O)Nc2c(C(=O)O)[nH]c3ccccc23)c(OC)c1
Answer: a. O=C(C1CCN(S(=O)(=O)c2cccc3cccnc23)CC1)N1CC=C(c2ccccc2)CC1
