Problem statement: Answer the multiple-choice question.
Question: Which drug has a -5.135\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(O)c1cccc(N2CCCC2)c1
b: CSc1ccc2c(c1)C(N1CCN(C)CC1)Cc1ccccc1S2.O=C([O-])/C=C\C(=O)[O-]
c: CC(C)(C)c1ccc(/C=N/NC(=O)C(=O)NCCCN2CCOCC2)cc1
Answer: a. O=C(O)c1cccc(N2CCCC2)c1
