Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.128\% 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) CCCC1=C([O-])C2N=CC=CC2=[N+](c2ccccn2)C1=O
b) C=CCOc1c(Br)cc(CNn2cn[nH]c2=S)cc1OC
Answer: a. CCCC1=C([O-])C2N=CC=CC2=[N+](c2ccccn2)C1=O
