Task: Answer the MCQ question.
Question: Which drug has a 21.046\% 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.) C=CCOc1ccc(/C=C/C(=O)Nc2ccc(C(=O)NC)cc2)cc1
b.) COc1cccc(-c2nnn(CC(=O)N3CCC(C)CC3)n2)c1
c.) Cn1c(=O)c2[nH]c(N=Nc3ccc(N)cc3N)nc2n(C)c1=O
Answer: c. Cn1c(=O)c2[nH]c(N=Nc3ccc(N)cc3N)nc2n(C)c1=O
