Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.759\% 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 other words.
Options:
(a) O=c1c2ccccc2cnn1Cc1n[nH]c(=S)n1-c1ccc(Cl)cc1Cl
(b) O=C1CCN(Cc2cccnc2)CCN1[C@H](CO)c1ccccc1
Answer: a. O=c1c2ccccc2cnn1Cc1n[nH]c(=S)n1-c1ccc(Cl)cc1Cl
