Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.392\% 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] CC(C)c1ccc(C(=O)N/N=C/c2cccc(Cl)c2Cl)cc1
[b] C(=C/c1ccccc1)\CSc1nc2ncccc2[nH]1
[c] CCCCN(CC)C(=O)Cn1nc(Cc2ccncc2)c2ccccc2c1=O
Answer: c. CCCCN(CC)C(=O)Cn1nc(Cc2ccncc2)c2ccccc2c1=O
