Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.681% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCNC(=O)/C(C#N)=C/c1c(N2CCOCC2)nc2ccccn2c1=O
b) Cc1nc2ccccc2nc1COc1ccc(C#N)cc1
c) CC(C)NC(=O)COC(=O)c1ccc(Cl)c(S(=O)(=O)N2CCCC2)c1
Answer: a. CCNC(=O)/C(C#N)=C/c1c(N2CCOCC2)nc2ccccn2c1=O
