Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.591\% 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] CCCc1nc(N2CCOCC2)c(C#N)c2c1CCCC2
[b] O=C(N/N=C/c1cn(-c2ccccc2)nc1-c1cc2ccccc2o1)c1ccccc1Br
Answer: a. CCCc1nc(N2CCOCC2)c(C#N)c2c1CCCC2
