Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 6.800\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) Cc1nn(C(=O)CN2C(=O)c3ccccc3C2=O)c(C)c1Br
b.) CCCCN(C(=O)c1ccc(N2CCCC2=O)cc1)c1c(N)n(CCC)c(=O)[nH]c1=O
c.) Cc1ccccc1-c1cc(C(=O)NCC2CC2)nn1CC1CC(c2cccc([N+](=O)[O-])c2)=NO1
Answer: a. Cc1nn(C(=O)CN2C(=O)c3ccccc3C2=O)c(C)c1Br
