Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.678\% 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: O=C(COC(=O)CNC(=O)C1CCCCC1)NCc1ccccc1
b: Cc1ccc(C(=O)OC(C)c2nc3ccccc3c(=O)[nH]2)o1
c: O=C(Nc1ccccc1-c1ccccc1)C1CCC1
Answer: a. O=C(COC(=O)CNC(=O)C1CCCCC1)NCc1ccccc1
