f A = set of all alphabet, then A is called:A.Finite setB.Infinite setC.Empty setD.Power set

To answer the question, we need to understand the definitions of the given options.

A. Finite set: A set that has a specific number of elements and can be counted.

B. Infinite set: A set that has an unlimited number of elements and cannot be counted.

C. Empty set: A set that has no elements.

D. Power set: The set of all possible subsets of a given set.

Now, let's analyze the given statement: "If A is the set of all alphabets..."

Since the set of all alphabets is infinite (as there is no limit to the number of alphabets), option A (finite set) can be eliminated.

The set of all alphabets is not empty, so option C (empty set) can also be eliminated.

Finally, the set of all alphabets does not include subsets, so option D (power set) can be eliminated.

Therefore, the correct answer is option B: Infinite set.
