Task: Answer the multiple choice question.
Question: Which drug has a 18.966% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(CCCn1c(=S)[nH]c2cc3c(cc2c1=O)OCO3)NCc1ccco1
b) COC(=O)CC1SC(=O)NC1=O
Answer: b. COC(=O)CC1SC(=O)NC1=O
