Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.430\% 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 other words.
Options:
[a] O=c1[nH]c(Nc2ccccc2)cc2cc(Br)ccc12
[b] O=[N+]([O-])c1cc2c(cc1/C=N/n1c(-c3ccccc3)n[nH]c1=S)OCO2
Answer: b. O=[N+]([O-])c1cc2c(cc1/C=N/n1c(-c3ccccc3)n[nH]c1=S)OCO2
