Task: Answer the multiple-choice question.
Query: Which drug has a 1.137\% 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 CCS(=O)(=O)N1CCN(c2ccc([N+](=O)[O-])c(NCc3ccccc3)c2)CC1
b O=C(NCCCCCCNC(=O)C1CCCC1)C1CCCC1
c O=C(NCCC[C@H]1CN2C(=NC[C@@H]2C2CCCCC2)N1CCc1ccc(Cl)c(Cl)c1)C1CCC1
Answer: a. CCS(=O)(=O)N1CCN(c2ccc([N+](=O)[O-])c(NCc3ccccc3)c2)CC1
