given the following venn diagram choose the correct set for M

The correct set for [tex]\bar{M}[/tex] is:
{2,5,6,8}
By looking at the Venn diagram we observe that:
The set M contain the elements:
M={9,3,4,7}
and set N contain the elements:
N={4,7,6}
Hence,
M∪N={9,3,4,7,6}
and the elements that come in the set:
[tex](M\bigcup N)^c[/tex] i.e. The elements in the Universal set excluding the elements of M∪N is: {2,5,8}
Hence, the elements that come in the set:
Complement of M i.e. [tex]\bar{M}[/tex] is:
The collection of all the elements excluding the elements of M.
Hence, the elements in complement of M are:
{2,5,6,8}
