Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 10.268\% 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=C1C(=O)N(CCCN2CCOCC2)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc2c(c1)OCCO2
b: COc1cc(/C=C2/C(=N)N3N=C(C)SC3=NC2=O)ccc1OS(=O)(=O)c1ccc(C)cc1
Answer: a. O=C1C(=O)N(CCCN2CCOCC2)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc2c(c1)OCCO2
