Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 18.134\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CNc1ccccc1
(b) CC(C)=CC(=O)Nc1ccccc1C(N)=O
(c) CC(C)(C)C(=O)Nc1ccc(C(=O)OC2CCCCC2)cc1
Answer: b. CC(C)=CC(=O)Nc1ccccc1C(N)=O
