Question about Kolb-experience learning

Hello Sir,

I bought the official ACCA practice test and there is a question I could not understand.
Could you please help me ?

Kolb’s learning cycle comprises active experimentation, experience, observation and reflection and which other element?

1)Positive reinforcement
2)Abstract conceptualisation
3)Application
4)Assimilation

The answer was “Abstract conceptualization” and the explanation is” The fourth element of Kolb’s experimental learning cycle is abstract conceptualisation”.

I was sure the answer was Application, because I read on the BPP that the formation of abstract conceptualization is the third element.

Could you please make this clear to me?

Thank you for your time

Cinzia
