Task: Answer the multiple choice question.
Query: Which drug has a 5.515\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. Cc1ccc(-c2ccc(C3C(C#N)=C(N)Oc4n[nH]c(C)c43)o2)cc1
b. O=CN1CCN(C(=O)c2cc3cc(Cl)ccc3[nH]2)CC1
c. CCOC(=O)C(C)Sc1nnc(Cc2cc(=O)[nH]c(=O)[nH]2)n1-c1cccc(OC)c1
Answer: b. O=CN1CCN(C(=O)c2cc3cc(Cl)ccc3[nH]2)CC1
