Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.514\% 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. C/C(N)=C(/C#N)C(=O)CSc1nnc(-c2ccc(OC(F)F)cc2)o1
b. Cc1ccc(-n2[nH]c(C)c(/C=N/Nc3ccc([N+](=O)[O-])cc3[N+](=O)[O-])c2=O)cc1
Answer: a. C/C(N)=C(/C#N)C(=O)CSc1nnc(-c2ccc(OC(F)F)cc2)o1
