Task: Answer the multiple choice question.
Question: Which compound has a 1.798\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) NC(=O)Cn1nc([N+](=O)[O-])nc1Oc1ccccc1F
(b) Cc1cc(=O)[nH]c(Nc2cccc(C(F)(F)F)c2)n1
(c) O=S(=O)(c1ccc(F)cc1)n1ccc(-c2cnc(-c3ccccc3)s2)n1
(d) CCOc1ccc(OCCNC(=O)C(NC(=O)c2c(F)cccc2F)C(C)C)cc1
(e) O=[N+]([O-])c1cccc(S(=O)(=O)Nc2ccc(-c3ccc(N4CCCC4)nn3)cc2)c1
Answer: c. O=S(=O)(c1ccc(F)cc1)n1ccc(-c2cnc(-c3ccccc3)s2)n1
