Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.914\% 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 other words.
Options:
a) O=C(/C=C\Nc1ccc2c(c1)OCO2)c1ccc2c(c1)OCO2
b) O=S(=O)(/N=C(\c1ccccc1)N1CCOCC1)c1ccc(Cl)cc1
Answer: a. O=C(/C=C\Nc1ccc2c(c1)OCO2)c1ccc2c(c1)OCO2
