Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.307\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COCCCNC(=S)N/N=C/c1ccc(O)cc1O
b. CCOC(=O)c1ccc(N2C(=O)C3CC=CCC3C2=O)cc1
Answer: a. COCCCNC(=S)N/N=C/c1ccc(O)cc1O
