Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.580\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C1/C(=C/c2ccc(F)cc2)CCC1C1CCCC1
b O=C(NNc1cc(Cl)cc(Cl)c1)c1cccs1
c COc1ccc2c(c1)Cc1sc(NC(C)=O)nc1-2
d Cc1cc(NC(=O)CSc2ccc3nnc(-c4cccc(F)c4)n3n2)no1
Answer: b. O=C(NNc1cc(Cl)cc(Cl)c1)c1cccs1
