Task: Answer the multiple-choice question.
Query: Which compound has a 2.197\% 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: CCCNC(=O)Cn1c(=O)/c(=C\c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)s/c1=C\C(=O)C(C)(C)C
b: CN1C(=S)SC(/[N+]([O-])=C\c2ccco2)C1(C)C
c: CCn1cnc2cc(NCc3ccncc3)ccc21
Answer: a. CCCNC(=O)Cn1c(=O)/c(=C\c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)s/c1=C\C(=O)C(C)(C)C
