Use These Sets to Find the Following $\mathrm { U } = \{ 5,6,7,8,9,10,11,12,13,14,15 \} , \mathrm { M } = \{ 5,7,9,11 \}$

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 5,6,7,8,9,10,11,12,13,14,15 \} , \mathrm { M } = \{ 5,7,9,11 \}$ , $\mathrm { N } = \{ 6,8,10,12,14 \}$ , $Q = \{ 5,7,9,11,13,15 \}$ , and $R = \{ 5,6,7,8 \}$ .
$\mathrm { M } \cap \mathrm { N }$

A) $\{ 5,6,7,8,9,10,11,12,14 \}$
B) $\{ 7,8,9,10,14 \}$
C) $\{ 6,7,8,9,10,11,12,13,14 \}$
D) $\varnothing ; M$ and $N$ are disjoint sets.
