Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.154\% 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, or c without using any other words.
Options:
a: CCN(Cc1nc(-c2cccc(C)c2)no1)C(=O)c1ccco1
b: CNC(=O)OCCc1nccn1C
c: Cc1ccc(C)c(NS(=O)(=O)c2cc(C(N)=O)ccc2C)c1
Answer: b. CNC(=O)OCCc1nccn1C
