Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -5.717\% 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 or b without using any other words.
Options:
a NC(N)=N/N=C/c1cccc(Cl)c1Cl
b CCCc1cc(C(=O)N2CCC(N3CCC(C(=O)NC(C)C)CC3)CC2)n(C)n1
Answer: a. NC(N)=N/N=C/c1cccc(Cl)c1Cl
