Use These Sets to Find the Following , And $R = \{ 9,10,11,12 \}$

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 9,10,11,12,13,14,15,16,17,18,19 \} , \mathrm { M } = \{ 9,11,13,15 \} , \mathrm { N } = \{ 10,12,14,16,18 \} , \mathrm { Q } = \{ 9,11,13,15,17,19 \}$ , and $R = \{ 9,10,11,12 \}$ .
$( \mathrm { R } \cup \mathrm { N } ) \cap \mathrm { M } ^ { \prime }$

A) M, or $\{ 9,11,13,15 \}$
B) $\varnothing$ , ' $^ { \prime }$ and ( $\left. \mathrm { N } \cup \mathrm { N } \right)$ are disjoint sets.
C) $\{ 9,10,12,14,16,18 \}$
D) $\mathrm { N }$ , or $\{ 10,12,14,16,18 \}$
