Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.356\% 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, b, or c without using any other words.
Options:
a: CCOC(=O)Cc1csc(NC(=S)NC(=O)c2ccc(F)cc2)n1
b: O=C(OCc1cnc(Cl)s1)c1ccccc1Cl
c: Cc1nc2c([nH]c3ccc(Br)cc32)s1
Answer: b. O=C(OCc1cnc(Cl)s1)c1ccccc1Cl
