Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.076% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1ccc(CCNC(=O)C(=O)NN=C2CCCCCCC2)cc1OC
(b) CC(=O)N1N=C(c2ccccc2)CC1c1ccc(F)cc1
(c) Cc1ncc([N+](=O)[O-])n1CC(=O)Nc1ccc(OC(F)(F)Cl)cc1
(d) CCSC1=NN1c1cc(C)nc(N)n1
(e) C/C(=N\NC(=O)Cc1c(C)[nH][nH]c1=O)c1cccc(Br)c1
Answer: c. Cc1ncc([N+](=O)[O-])n1CC(=O)Nc1ccc(OC(F)(F)Cl)cc1
