Problem statement: Answer the multiple-choice question.
Query: Which drug has a 7.849\% 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 Cc1cccc(N2C(=S)N=C(Nc3c(C)cccc3C)C23CCOC(C)(C)C3)c1
b CCCc1[nH]nc2c1C(c1ccc(Br)s1)C(C#N)=C(N)O2
Answer: b. CCCc1[nH]nc2c1C(c1ccc(Br)s1)C(C#N)=C(N)O2
