Task: Answer the multiple-choice question.
Question: Which drug has a 3.727\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a Cc1[nH]n(-c2ccccc2)c(=O)c1C=Nc1ccc(S(=O)(=O)NC(N)=O)cc1
b COc1cccc(/C=N/Nc2nc(Nc3ccc([N+](=O)[O-])cc3)nc(N3CCCC3)n2)c1O
c O=C1CC(=O)N(c2ccccc2)N1c1ccccc1
Answer: c. O=C1CC(=O)N(c2ccccc2)N1c1ccccc1
