Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.482\% 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] CCCCN(C(=O)c1ccc2c(c1)OCO2)c1c(N)n(CCCC)c(=O)[nH]c1=O
[b] NS(=O)(=O)c1ccc(N/C=C\C(=O)c2ccc(F)cc2)cc1
Answer: a. CCCCN(C(=O)c1ccc2c(c1)OCO2)c1c(N)n(CCCC)c(=O)[nH]c1=O
