Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.904\% 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 or b without using any additional words.
Options:
a) CCOC(=O)C1=C(C)NC(=O)C(C#N)C1c1ccco1
b) O=C(CNC(=O)c1ccc2c(c1)OCCO2)N/N=C/c1cccc(Br)c1
Answer: a. CCOC(=O)C1=C(C)NC(=O)C(C#N)C1c1ccco1
