Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.431\% 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 other words.
Options:
(a) O=C(N=Nc1c(O)[nH]c2ccc(Cl)cc12)c1cc(-c2cccs2)nc2ccccc12
(b) O=C(O)CCCCCCCCCCP(=O)(c1ccccc1)c1ccccc1
(c) CCOC(=O)N1CCN(CC(=O)c2ccc(O)c(C)c2O)CC1
(d) COc1nc2ccccc2c(=O)n1OCC(C)C
(e) COc1ccc([C@H]2CC(=O)C=C(c3ccc(Cl)c(C(F)(F)F)c3)C2)cc1
Answer: c. CCOC(=O)N1CCN(CC(=O)c2ccc(O)c(C)c2O)CC1
