Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 4.812\% 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: CCOC(=O)c1c(-c2ccc(F)cc2)csc1/N=C/N(C)C
b: CN(C)CCN(C(=O)c1ccc(S(=O)(=O)N(C)c2ccccc2)cc1)c1nc2cc3c(cc2s1)OCCO3.Cl
Answer: a. CCOC(=O)c1c(-c2ccc(F)cc2)csc1/N=C/N(C)C
