Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.330\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(CN1CCOCC1)Nc1ccc(NC(=O)CN2CCOCC2)c(Cl)c1
b. Cc1ccc(-c2nc(C3CCCN(S(=O)(=O)c4ccc(C)cc4)C3)no2)cc1
Answer: a. O=C(CN1CCOCC1)Nc1ccc(NC(=O)CN2CCOCC2)c(Cl)c1
