Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.919\% 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, c, or d without using any other words.
Options:
[a] Cc1ccc(S(=O)(=O)N2CCN(C(=O)Cc3c(F)cccc3Cl)CC2)cc1
[b] CNC(=O)CNC(=O)Nc1ccc(Cl)c(Cl)c1
[c] O=C(/C=C1\SC(=O)NC1=O)Nc1ccc(C(=O)O)cc1
[d] CCCc1[nH]nc2c1C(c1ccc(OC)cc1OC)C(C#N)=C(N)O2
Answer: b. CNC(=O)CNC(=O)Nc1ccc(Cl)c(Cl)c1
