Task: Answer the multiple choice question.
Question: Which compound exhibits a -5.687\% 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 Cc1cccc(C)c1NC(=O)COC(=O)CNC(=O)C1CCCCC1
b COc1ccc2c(c1)c(CC[NH3+])c(C)n2Cc1ccccc1.[Cl-]
c O=C(CN1CCN(c2ccccc2O)CC1)NC(c1ccccc1)c1ccccc1
Answer: c. O=C(CN1CCN(c2ccccc2O)CC1)NC(c1ccccc1)c1ccccc1
