Task: Answer the multiple-choice question.
Query: Which drug has a 18.049\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOC(=O)NC1(C(F)(F)F)NC(=O)N(c2ccc(F)cc2)C1=O
b: COc1cc(C#N)c(NS(=O)(=O)c2ccc3[nH]c(=O)sc3c2)cc1OC
Answer: b. COc1cc(C#N)c(NS(=O)(=O)c2ccc3[nH]c(=O)sc3c2)cc1OC
