Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.453\% 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) O=C(Nc1nc2c(s1)CCCC2)c1cc(-c2ccccc2)nc2ccccc12
b) O=S(=O)(NC1CCN(Cc2ccccc2)CC1)c1ccc(Cl)cc1
Answer: a. O=C(Nc1nc2c(s1)CCCC2)c1cc(-c2ccccc2)nc2ccccc12
