Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.221\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCn1c(N)c(Br)c(=O)[nH]c1=O
(b) CCOc1ccc(C(=O)OCC(=O)NC(C)C)cc1
(c) Cc1cccc(N=Nc2c(C)[nH]n(C(N)=S)c2=O)c1C
