The most appropriate option for the following sets
$A$ is set of letters of the word 'debit card'
$B$ is the set of letters of the word 'bad credit'

• A. $A$ and $B$ are equivalent sets
• B. $A$ and $B$ are unequal sets
• C. $A$ and $B$ are disjoint sets
• D. $A$ and $B$ are identical sets

Answer 1

The correct option is D $A$ and $B$ are identical sets

$A=\{a,b,c,d,e,i,t,r\};B=\{a,b,c,d,e,i,t,r\}$
$\therefore A=B\Rightarrow A$ and $B$ are equivalent and identical sets
$\therefore$ Most appropriate answer is identical sets.
