C Is a infinite set

Step-by-step explanation:

Hope it is help u

Answer 2

$\huge\star{\green{\underline{\mathfrak{Answer :-}}}}$

Set A = {1,2,3,4,5} is finite set because the elements present in the set are countable.

Set B = {a,b,c,d,e,g} is finite set because the elements again here are countable.

Set C = {men living presently in different parts of the world}

• There are infinite places in the world.
• The population of the place is the men living in the place.
• The population differs from place to place.
• As there are infinte places in the world, obviously I am going to be infinite types of population in different places of the world.
• Hence, the elements for this set will be infinite, making it an infinite set, because internet means uncountable, countable number of elements in set makes it infinite set.
