Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.296\% 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. O=C(O)c1ccc(-c2noc(-c3ccc(F)cc3)n2)cc1
b. COc1ccc(NC(=O)CCn2nnc(-c3ccc(C)cc3)n2)cc1OC
c. Cc1ccc(S(=O)(=O)N2CC=C(C(=O)NC3CCCC3)CC2)cc1
Answer: b. COc1ccc(NC(=O)CCn2nnc(-c3ccc(C)cc3)n2)cc1OC
