Task: Answer the multiple-choice question.
Question: Which drug has a 4.505\% 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 other words.
Options:
a.) COCC(=O)NCCc1ccc(S(N)(=O)=O)cc1
b.) COc1cc(C2NC(=O)C(C#N)=C(Nc3cccc(C)c3)S2)ccc1O
c.) CC(=O)Nc1cccc(NC(=O)c2cc(C)on2)c1
d.) C#CCOc1ccc(Br)cc1/C=N/O
Answer: d. C#CCOc1ccc(Br)cc1/C=N/O
