Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.012\% 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 additional words.
Options:
a O=[N+]([O-])/C=C1\NCCN1Cc1ccc(Cl)nc1
b Cc1sc2ncnc(OCC(=O)N3CCN(S(=O)(=O)c4ccccc4)CC3)c2c1C
Answer: a. O=[N+]([O-])/C=C1\NCCN1Cc1ccc(Cl)nc1
