Problem statement: Answer the multiple-choice question.
Query: Which drug has a -4.766\% 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=C(NCc1cccs1)C1CC(c2ccc(Cl)c(Cl)c2)=NO1
b) O=c1c2c([nH]c3ccccc13)C(=C1CCCC1)CC2
Answer: b. O=c1c2c([nH]c3ccccc13)C(=C1CCCC1)CC2
