Infinite is something that becomes large beyond bound.
It is having no limits or boundaries in time or space or extent or magnitude.
It is just the opposite of finite.
Consider 1, 2, 3, 4, 5, 6, 7, 8, 9....
Here, the number increases by 1 and it has no limits or boundaries.
Hence, the number is infinite as this count is unlimited and it will go forever.
A. P = {Set of natural numbers}
B. Q = {Set of vowels}
C. R = {Set of consonants}
D. S = {Set of prime numbers less than 20}
Correct Answer: A
Step 1: Something infinite has no limits or boundaries.
Step 2: Here, the set of natural numbers contains infinite number of elements.
Step 3: Hence, P = {Set of natural numbers} is an infinite set.
