Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.687\% 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. OCC[C@H]1C[C@@H](O)[C@H](O)[C@]2(Cc3ccccc3O2)O1
b. COc1ccc(NC(=O)[C@H](COCc2ccccc2)NC(=O)OC(C)(C)C)cc1
c. CCn1c(CC(=O)Nc2ccc(Cl)cc2)nnc1SCC(=O)N1CCOCC1
d. CCCCOc1ccc(NC(=O)CSc2cccc3cccnc23)cc1
e. CSc1ccccc1NC(=O)CN(C)CC(=O)Nc1ccc(Cl)cc1[N+](=O)[O-]
Answer: a. OCC[C@H]1C[C@@H](O)[C@H](O)[C@]2(Cc3ccccc3O2)O1
