Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.378\% 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(NCc1cccnc1)c1ccc(-c2cccc(Cl)c2Cl)o1
(b) CCOc1cc(CNS(=O)(=O)c2cn(C)cn2)cc(OCC)c1OCC
Answer: a. O=C(NCc1cccnc1)c1ccc(-c2cccc(Cl)c2Cl)o1
