Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.120\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: C/C(=N\NC(=O)CC1N=C(Cc2ccccc2)NNC1=O)c1ccc(Cl)cc1Cl
b: N#CCC(=O)Nc1ccc(C(F)(F)F)cc1N1CCOCC1
Answer: a. C/C(=N\NC(=O)CC1N=C(Cc2ccccc2)NNC1=O)c1ccc(Cl)cc1Cl
