Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.430\% 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) CCN1CC2=C(OC(N)=C(C#N)C2c2cccs2)/C(=C\c2cccs2)C1
(b) CSCCC(NC(=O)c1ccccc1Br)C(=O)NC(C)CCc1ccccc1
Answer: a. CCN1CC2=C(OC(N)=C(C#N)C2c2cccs2)/C(=C\c2cccs2)C1
