Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.426\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccc(Cn2c(SCc3cc(C)ccc3C)nc3cc(OC)c(OC)cc3c2=N)cc1
b) COc1cccc(NS(=O)(=O)c2ccc3c(c2)CCCN3C(C)=O)c1
c) O=[N+]([O-])c1ccc(-c2nnc(CNC3CCCC3)o2)cc1
d) CCc1cc(Br)ccc1NC(=O)C1CCCO1
Answer: c. O=[N+]([O-])c1ccc(-c2nnc(CNC3CCCC3)o2)cc1
