Task: Answer the MCQ question.
Query: Which drug has a 7.376\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCOC(=O)C1=C(CSc2nc(CC)c(C)cc2C#N)OC(N)=C(C#N)C1c1ccc(OC)cc1
[b] S=c1[nH]nc(-c2ccccc2)n1C1C=CCCC1
Answer: a. CCOC(=O)C1=C(CSc2nc(CC)c(C)cc2C#N)OC(N)=C(C#N)C1c1ccc(OC)cc1
