Problem statement: Answer the multiple-choice question.
Question: Which drug has a -1.847\% 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 COC(=O)c1ccccc1NC(=S)N(Cc1ccc2c(c1)OCO2)Cc1cc2cc(C)ccc2[nH]c1=O
b COc1cccc(C2C3CN(C)CC=C3C(C#N)=C(N)C2(C#N)C#N)c1OC
Answer: b. COc1cccc(C2C3CN(C)CC=C3C(C#N)=C(N)C2(C#N)C#N)c1OC
