Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.978\% 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 Clc1ccccc1-c1nn2c(-c3ccncc3)nnc2s1
b COc1ccccc1N(C(=O)c1snc(C(N)=O)c1N)C(C(=O)NCCC(C)C)c1ccco1
c NNc1cc(C(=O)O)ccc1Cl
Answer: b. COc1ccccc1N(C(=O)c1snc(C(N)=O)c1N)C(C(=O)NCCC(C)C)c1ccco1
