Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.435\% 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 additional words.
Options:
a) O=c1c(Cc2ccccc2)c(O)c2cccc3c4c(n1c23)CCCC4
b) Cc1nc2c(Cl)c(C)nn2c2c1CCC2
Answer: a. O=c1c(Cc2ccccc2)c(O)c2cccc3c4c(n1c23)CCCC4
