Task: Answer the multiple-choice question.
Query: Which compound has a 0.172\% 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.) CCS(=O)(=O)NCc1nnc2n1-c1ccc(Br)cc1C(c1ccccc1Cl)=NC2
b.) O=C(/C=C/c1ccco1)N1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1
Answer: b. O=C(/C=C/c1ccco1)N1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1
