Task: Answer the multiple-choice question.
Question: Which compound exhibits a 23.490% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C1CNC(=O)/C1=C/c1ccccc1
(b) O=C(O)c1ccc(N2CCN(C(c3ccccc3)c3ccccc3)CC2)c([N+](=O)[O-])c1
(c) CC(=O)NCCC(=O)Nc1nc(-c2ccccc2Cl)cs1
Answer: a. O=C1CNC(=O)/C1=C/c1ccccc1
