Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 14.382\% 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)CN1NC2(CCCCC2)NC1=S
b: COc1cccc(N(C(=O)c2snc(C(N)=O)c2N)C(C(=O)NCC2CCCO2)c2cccs2)c1
Answer: a. CCOC(=O)CN1NC2(CCCCC2)NC1=S
