Task: Answer the multiple choice question.
Question: Which compound exhibits a 27.904\% 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, or c without using any additional words.
Options:
a Cc1cc(C)n2c(Br)c(CN3CCCC(C)C3)nc2n1
b CCOc1ccccc1CN1CCN(C2CCOCC2)CC1CCO
c O=C(c1cnc(-c2ccc(Cl)cc2)s1)c1ccc(Cl)cc1Cl
Answer: a. Cc1cc(C)n2c(Br)c(CN3CCCC(C)C3)nc2n1
