Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.994\% 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.) CCOC(=O)c1c(N)sc(C(=O)Nc2ccccc2F)c1C
b.) N#Cc1ccc(C(=O)CSc2n[nH]c(=O)n2-c2cccnc2)cc1
Answer: a. CCOC(=O)c1c(N)sc(C(=O)Nc2ccccc2F)c1C
