Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.007\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) Cc1c(Cl)c([N+](=O)[O-])nn1CCCC(=O)N(Cc1ccccc1)Cc1ccccc1
(b) CN=C1SC(CC(=O)Nc2ccc(F)cc2F)C(=O)N1/N=C/c1ccc(OC(F)F)c(OC)c1
(c) CCCCN(C)C(=O)Cn1nc(-c2ccc(Cl)cc2)ccc1=O
Answer: c. CCCCN(C)C(=O)Cn1nc(-c2ccc(Cl)cc2)ccc1=O
