Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.750\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CC(C)N1C(=O)CCC1C(=O)NC1CCCC1
b) CC(=O)Nc1ccc(S(=O)(=O)NCC(=O)OCC(=O)N2CCN(c3ccccc3)CC2)cc1
c) CCOC(=O)C(/C=N/c1cc(C)nn1-c1ccccc1)=C(\C)O
Answer: a. CC(C)N1C(=O)CCC1C(=O)NC1CCCC1
