Problem statement: Answer the multiple choice question.
Question: Which drug has a -8.024\% 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 other words.
Options:
a O=C(c1c(Cl)cccc1Cl)N1CCN(c2ccccn2)CC1
b CNC(=S)N(CCc1c(C)[nH]c2ccccc12)Cc1ccco1
Answer: a. O=C(c1c(Cl)cccc1Cl)N1CCN(c2ccccn2)CC1
