Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.985\% 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) CC(C)c1ccc(C(O)c2nc3ccccc3n2C)cc1
b) O=c1c2c(n3cnnc3n1-c1ccccc1)-c1ccccc1CC21CCCCC1
Answer: b. O=c1c2c(n3cnnc3n1-c1ccccc1)-c1ccccc1CC21CCCCC1
