Use These Sets to Find the Following $\mathrm { U } = \{ 8,9,10,11,12,13,14,15,16,17,18 \} , \mathrm { M } = \{ 8,10,12,14 \} , \mathrm { N } = \{ 9,11,13,15,17 \}$

Multiple Choice

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 8,9,10,11,12,13,14,15,16,17,18 \} , \mathrm { M } = \{ 8,10,12,14 \} , \mathrm { N } = \{ 9,11,13,15,17 \}$ , $Q = \{ 8,10,12,14,16,18 \}$ , and $R = \{ 8,9,10,11 \}$ .
$( \mathrm { U } \cup \varnothing ) \cap \mathrm { R } ^ { \prime }$

A) $\mathrm { R }$ , or $\{ 8,9,10,11 \}$
B) $U$ , or $\{ 8,9,10,11,12,13,14,15,16,17,18 \}$
C) $\{ 12,13,14,15,16,17,18 \}$
D) $\varnothing$ ; $R ^ { \prime }$ and $( \mathrm { U } \cup \varnothing )$ are disjoint sets.
