Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.689\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(NC(=O)c1ccccc1NS(C)(=O)=O)c1ccccc1
[b] CCn1c(-c2nn(C)cc2Cl)n[nH]c1=S
[c] COc1ccccc1C(=O)N1CCCC(c2nc(-c3cc(OC)c(OC)c(OC)c3)no2)C1
Answer: b. CCn1c(-c2nn(C)cc2Cl)n[nH]c1=S
