Task: Answer the multiple choice question.
Question: Which drug has a 13.873\% 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 additional words.
Options:
a.) CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)[C@H](C)NC(=O)c1ccco1
b.) CCCCCC(=O)NNC(=S)NC(=O)c1ccccc1[N+](=O)[O-]
c.) O=C(Nc1ccc(F)cc1)Nc1ccccc1NS(=O)(=O)c1cccs1
d.) O=C(c1cccc(S(=O)(=O)Nc2cccc(C(F)(F)F)c2)c1)N1CCOCC1
e.) CC(C)=C1SC(N2CCN(c3cccc(Cl)c3)CC2)=NC1=O
Answer: b. CCCCCC(=O)NNC(=S)NC(=O)c1ccccc1[N+](=O)[O-]
