Use These Sets to Find the Following , And $R = \{ 3,4,5,6 \}$

Multiple Choice

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 3,4,5,6,7,8,9,10,11,12,13 \} , \mathrm { M } = \{ 3,5,7,9 \} , \mathrm { N } = \{ 4,6,8,10,12 \} , \mathrm { Q } = \{ 3,5,7,9,11,13 \}$ , and $R = \{ 3,4,5,6 \}$ .
$\varnothing \cup N$

A) $\varnothing ; \mathrm { N }$ and $\varnothing$ are disjoint sets.
B) $\{ 5,7,9,11,13 \}$
C) $\mathrm { N }$ , or $\{ 4,6,8,10,12 \} ; \mathrm { N }$ and $\varnothing$ are disjoint sets.
D) $\{ 3,4,5,6,7,8,9,10,11,12,13 \}$
