Problem statement: Answer the multiple choice question.
Query: Which drug has a -34.676\% 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 additional words.
Options:
(a) CN(C)CCN(C(=O)C1CCN(S(=O)(=O)c2cccs2)CC1)c1nc2ccc(F)cc2s1.Cl
(b) O=C(c1cc(F)c(F)cc1Cl)N1CCN(CCc2ccccc2)CC1
Answer: b. O=C(c1cc(F)c(F)cc1Cl)N1CCN(CCc2ccccc2)CC1
