Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 17.064% 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 other words.
Options:
(a) CCCCc1nnc(NC(=O)C=C(C)C)s1
(b) O=C1/C(=C/c2cccc(F)c2)Oc2cc(O)ccc21
(c) Cc1ccc(C)c(NS(=O)(=O)c2ccc(NC(=O)c3ccco3)cc2)c1
(d) CCOc1c(Br)cc(C(N)=O)cc1OC
(e) O=C(NCc1cn2ccsc2n1)Nc1ccc(Cl)cc1
Answer: d. CCOc1c(Br)cc(C(N)=O)cc1OC
