The difference between "kind of + article" and "kind of"

[Unregistered]

Hello!

I speak English as a foreign language and I am very puzzled because I cannot grasp the difference between the following sentences:

A) "What kind of object is it?"

B) "What kind of an object is it?"

I have seen both forms being used but I just cannot understand the difference. Could somebody please help me and explain what is going on here?

Many many thanks!
