Task: Answer the MCQ question.
Query: Which drug exhibits a 7.983\% 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 C=CCn1c(=O)c2c(nc(Br)n2Cc2ccccc2Cl)n(C)c1=O
