Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.061\% 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, b, c, or d without using any additional words.
Options:
(a) O=C(N/N=C/c1cc2c(cc1Cl)OCO2)c1cccc(Br)c1
