${\sf{\pink{\underline{\Large{Explanation}}}}}$

we make this question by two methods

• By vein diagram
• or by visualisation

first method

$\tt{A\cap\emptyset=\emptyset}$

• Let visualise
• There are a set which have some element
• and other set which have empty and nothing
• we have to find common point between them
• But one set is empty
• Therefore there is no any common points or area..
