Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.580\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(COC(=O)Cc1ccc(S(=O)(=O)N2CCOCC2)s1)NCCc1ccccc1
b: COC(=O)Nc1sc2c(c1C(=O)N1CCOCC1)CCC(C)C2
Answer: a. O=C(COC(=O)Cc1ccc(S(=O)(=O)N2CCOCC2)s1)NCCc1ccccc1
