# Find the intersection of each pair of the following set : A={a,e,i,o,u},B={a,b,c}

$\begin{array}{1 1}(A)\;\{a,e,i,o,u\}&(B)\;\{a,b,c,e,i,o,u\}\\(C)\;\{a,b,c\}&(D)\;\{a\}\end{array}$

A={a,e,i,o,u}
B={a,b,c}
a is the only element which is common to both A and B set.
$\therefore A\cap B=\{a,e,i,o,u\} \cap \{a,b,c\}$
$\Rightarrow \{a\}$
Hence (D) is the correct answer.
