Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -0.813\% 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) CCOC(=O)c1sc(C)c(C(N)=O)c1NC1=NCCCCC1
(b) Cn1c(C(=O)N(Cc2ccccc2)Cc2cccs2)cc2sccc21
(c) O=C(NNC(=O)c1cc(-c2ccccc2)nc2ccccc12)Nc1cccc(Cl)c1
Answer: c. O=C(NNC(=O)c1cc(-c2ccccc2)nc2ccccc12)Nc1cccc(Cl)c1
